A Case of Growing Pains
When he first opened his own business, Dionysus loved it. He went to work early in the morning and did not leave until after 9.00P.M. To spend time with his family, he would take off a few hours in the afternoon and then return to the store after supper, staying until closing time. When he was away from the store in the late afternoon, part-time personnel handled the operation. That was five years ago. Since then, Dionysus’s business has grown tremendously. Now he employs eight full-time people and sells seven times as much as he did originally. With this increase in business, however, have come a lot of headaches. In particular, Dionysus has to make many more decisions than he did before. Additionally, although he wants to get his employees involved in the decision-making process and not do all of the work himself, he feels he must do many tasks on his own. He does not believe he can delegate much authority. For example, Dionysus still makes all of the decisions regarding purchasing, pricing, advertising, hiring, and merchandise display, and he still sells goods in the store. Recently, Dionysus went to the doctor for his annual physical. The doctor told him he was working too hard and had to start slowing down. “You’ve been running that store singlehanded for as long as I can remember,” the doctor said. “You’ve got lots of help in the store. Start relying on them to help you out.” Dionysus did not disagree. The doctor offered good advice, and Dionysus knows the has to start delegating more authority and getting out of the actual hustle-bustle of daily activity. However, this worries him. A few months ago, he tried turning over more work to his employees and staying in the background. During that time, he concerned himself with the overall operation of the store and left the minor day-to-day business to the staff. But Dionysus was bored with this side of the operation. He wants to be active-active role in the business, not just to sit in the sidelines. Second, he wants to be in the forefront of the action, like he always has been. Dionysus does not know how to resolve this dilemma. He would like to maintain his level of involvement at the shop but realizes that, for health reasons, this is inadvisable. However, to
be a manager in the true sense of the word seems boring to him.

Question 1
The Covid-19 pandemic in the first half of 2020 has significantly changed the business
landscape globally and locally. Businesses struggle to survive and share prices of companies
continue to tumble.
This situation, however, presents good investment opportunities for PropThrive Pte Ltd
(PropThrive). PropThrive is an investment holding company which invests in companies with
strong fundamentals and promising growth opportunities. Given the current depressed share
prices, the Chief Investment Officer (CIO) thinks that now is a good time to buy into shares of
such companies.
You have recently been recruited as a financial analyst of PropThrive. You report to Peter Tan,
one of the two investment strategists of PropThrive. In a recent meeting you attended with
Peter, both the CIO and the Chief Financial Officer (CFO) have identified Kitchen Culture
Holdings Ltd. (Kitchen Culture) as a promising investment target. Their rationale was that
despite the continuing losses experienced by Kitchen Culture, it has a strong reputation.
Moreover, the pandemic has kept the people around the world indoor more and this trend is
here to stay. People tend to cook more when they stay indoor and consequently, the demand
for good quality kitchen appliances will continue to rise.
The CFO and CIO have requested you and Peter Tan to examine and report to them on the
performance and financial position of Kitchen Culture. Your report should include a full
analysis and preliminary conclusion to be used by the CFO and CIO in their investment
decision.
Peter Tan has requested that you obtain the two most recent annual reports of Kitchen Culture
that include the financial statements for the financial periods ended 30 June 2019 (FY2019),
30 June 2018 (FY2018) and 30 June 2017 (FY2017) respectively, and any other relevant
materials of Kitchen Culture to start helping him to analyse and draft the report.
As this is the first time you are preparing such a report, Peter Tan has given you some advice
which you should heed. You are free to decide the relevant financial tools to use for your
analysis and assessment. As this is a formal report, the contents should be succinct and
professional. You should also use a proper format and limit your word count to no more than
1,000. All detailed computations, tables and charts should be in appendices to avoid distracting
readers from the main key points.
Peter also advised you that unless unavailable, all information, data and documents should be
obtained from reliable sources like the Singapore Exchange website. This is the url link to the
said website: https://www.sgx.com/securities/annual-reports-related-documents. Peter has also
furnished the SGInvestors.io website url for you to obtain the share prices of listed companies
in Singapore: https://sginvestors.io/sgx/stock-listing/alpha.
Required:
Peter specified that the report must include the following components:

(a) Analyse and discuss the profitability; liquidity and efficiency; and solvency of Kitchen
Culture.

(b) Appraise whether Kitchen Culture is a good investment option and state your
preliminary conclusion. Besides the quantitative data, you should also use qualitative
information to support your preliminary conclusion.

1. Complete Part I of this assignment first, if you have not done so, because it provides guided practice on questions similar to the questions in Part II here.
2. Check out the “Important Resources and Assignment Guides” in the Modules section on Canvas to see how to properly show your math work. There are also examples of the APA-style tables and graphs (figures) for your reference.
3. Your submitted assignment must be in Word format, with a clear answer typed out for each question, even if you show math work in a separate Excel file.

Q1) One-Sample t-Test (21 points total)

I am curious about how many hours per week my students spend on their online coursework. So, I surveyed 9 of my students on how many hours per week they spend on my online PSY 230 course. According to a survey of online college students (in all courses), students studied an average of 9 hours a week for a 3-credit course. I assume that the national study time scores are normally distributed, and I set the significance level at α = .05.

1. What is the dependent variable in this hypothesis test? What is the “sample” for this one-sample t test? (2 points total: 1 for each question)

2. I am interested in testing whether there are any differences between my students and the national average, so my hypothesis is non-directional. What would be the null and alternative hypotheses in both words and symbol notations for my analysis? (4 points total: 1 for each hypothesis in words, 1 for each hypothesis in notation)

3. Calculate the sample mean. (2 points total: 1 for work, 1 for answer)

4. Estimate the standard deviation of the population (2 points total: 1 for work, 1 for answer)

5. Calculate the standard error (standard deviation of the sampling distribution) (2 points total: 1 for work, 1 for answer)

6. Calculate the t statistic for the sample (2 points total: 1 for work, 1 for answer)

7. Specify whether the test is a one-tailed or two-tailed test based on the hypotheses form (b), and then determine the critical t value(s) based on the type of test and the preset alpha level (2 points total: 1 for each answer)

8. Compare the t statistic with the critical t value. Is the calculated t statistic more extreme or less extreme than the critical t value? Then make a decision by stating whether we “reject” or “fail to reject” the null hypothesis (2 points total: 1 for each answer)

1. Interpret the result in 1-2 sentences (you may restate the hypothesis accepted or explain it in your own words) (1 point)

10. Calculate the raw effect size and the standardized effect size of this hypothesis test (4 points total: 2 per effect size: 1 for work, 1 for answer)

data

USE R to do it will soon, and if you use r, could you give me a code

Suppose that a clinical psychologist is interested in comparing the relative effectiveness of two forms of psychotherapy (cognitive-behavioral and assertiveness training) in combination with three different medications (Zoloft, Prozac, and Lexapro) for alleviating depression. Thirty-six individuals are randomly sampled and randomly assigned a combination of treatment. The Depression Scale of MMPI serves as the response (score). The goal is to lower the score.

(a) Write out the initial hypotheses to be tested in words.


(b) Write out the appropriate statistical model and explain all terms. (Let i be associated with therapy)


(c) Construct an interaction plot where medication is the “trace factor”. Based on the plot, does there appear to be evidence of an interaction? Hint: Since there are 3 different medications, you’ll have to modify the following arguments for the code in R for the interaction plot to ensure that all 3 types of medication the are plotted. Note that you can use any number in the pch argument and any colors in the col argument. You will need to save this as a PDF, Word doc, or png.

The code here is for two levels: pch=c(1,2), col = c("red", "blue")

What can you do for three levels?

(d) Calculate the degrees of freedom for each term including the residual. Make sure to show work on how you calculated the degrees of freedom. Source Degrees of Freedom

Note: The sample size is 36

(e) Obtain the ANOVA table in R and confirm the degrees of freedom you reported in part (d). Should the main effects or simple effects be analyzed?



(f) Based on your answer above, report the appropriate results. If the main effects are appropriate, specify the estimated difference in average score for the therapies and/or medications along with the corresponding 95% confidence intervals for those which are statistically different. If the simple effects are appropriate, provide the estimated difference in average scores at a given type therapy along with the corresponding 95% confidence intervals for those which are statistically different.


(g) If a psychiatrist is currently using assertiveness training with a patient and currently has access to Prozac, should they switch their patient to using Prozac instead of Lexapro? Justify your answer

The Marburg Colloquy, 1529 The Hessian Chancellor Feige: My gracious prince and lord [Landgrave Philip of Hesse] has summoned you for the express and urgent purpose of settling the dispute over the sacrament of the Lord’s Supper.... Let everyone on both sides present his arguments in a spirit of moderation.... Now then, Doctor Luther, you may proceed. Luther: Noble prince, gracious lord! Undoubtedly the colloquy is well intentioned.... Although I have no intention of changing my mind, which is firmly made up, I will nevertheless present the grounds of my belief and show where the others are in error.... Your basic contentions are these: In the last analysis you wish to prove that a body cannot be in two places at once, and you produce arguments about the unlimited body which are based on natural reason. I do not question how Christ can be God and man and how the two natures can be joined. For God is more powerful than all our ideas, and we must submit to his word. Prove that Christ’s body is not there where the Scripture says, “This is my body!” Rational proofs I will not listen to.... It is God who commands, “Take, eat, this is my body.” I request, therefore, valid scriptural proof to the contrary. Zwingli: I insist that the words of the Lord’s Supper must be figurative. This is ever apparent, and even required by the article of faith: “taken up into heaven, seated at the right hand of the Father.” Otherwise, it would be absurd to look for him in the Lord’s Supper at the same time that Christ is telling us that he is in heaven. One and the same body cannot possibly be in different places.... Luther: I call upon you as before: your basic contentions are shaky. Give way, and give glory to God! Zwingli: And we call upon you to give glory to God and to quit begging the question! The issue at stake is this: Where is the proof of your position? I am willing to consider your words carefully—no harm meant! You’re trying to outwit me.... You’ll have to sing another tune. Luther: You’re being obnoxious. Zwingli: (excitedly) Don’t you believe that Christ was attempting in John 6 to help those who did not understand? Luther: You’re trying to dominate things! You insist on passing judgment! Leave that to someone else! ... It is your point that must be proved, not mine. But let us stop this sort of thing. It serves no purpose. Zwingli: It certainly does! It is for you to prove that the passage in John 6 speaks of a physical repast. Luther: You express yourself poorly and make about as much progress as a cane standing in a corner. You’re going nowhere. Zwingli: No, no, no! This is the passage that will break your neck! Luther: Don’t be so sure of yourself. Necks don’t break this way. You’re in Hesse, not Switzerland.

How did the positions of Zwingli and Luther on the sacrament of the Lord’s Supper differ? What was the purpose of this debate? Based on this example, why do you think Reformation debates led to further hostility rather than compromise and unity between religious and sectarian opponents? What implications did this have for the future of the Protestant Reformation?

Part #2: Creating a table

Background: Prior to storing data in a RDBMS, a table with suitable schema must be created.

Exercise: Create a table with your ID (e.g.: derricker) with the following procedure

1. If needed, log onto MySQL RDBMS using the mysql command-line.
2. Create a table to store person information (namely: id, name, and email) by appropriately changing ID in the following command:

4. If the table is successfully created, you should get the message "Query OK, 0 rows affected". If you get an error, get help from to resolve the error.

Part #3: Insert some data into your table

Background: One of the key operations of working with a database is inserting new values into the database. This is accomplished using SQL insert statement.

Exercise: Insert sample data into your ID table that you created in the previous step with the following command:

1. If needed, log onto MySQL RDBMS using the mysql command-line introduced earlier.
2. Insert a row into the table using the SQL insert statement below:

3. Check to ensure that you get "Query OK, 1 row affected" as the response indicating 1 row was successfully inserted. If you get errors get help from your instructor to resolve the issue.
4. Suitably modify the insert command to insert the following 3 rows to your table:

Part #4: Experiment with SQL queries

Background: Querying data using SQL involves coding suitable SELECT statements with necessary columns and conditions.

Exercise: Using the SELECT statements discussed in class, code the SQL statement for the following queries:

1. Develop a SQL query to list all rows in your table (copy-paste your SQL statement and output in the space below):

2. Develop a SQL query to list just name of persons with ID less than 400 (copy-paste your SQL statement and output in the space below):

3. Develop a SQL query to list id and name of persons that have the word 'Doe' in their name using the LIKE comparison operator (copy-paste your SQL statement and output in the space below):

4. Develop a SQL query to list id and name of persons, with data sorted by name (copy-paste your SQL statement and output in the space below):

Curve-fitting Project - Linear Model

Instructions

For this assignment, collect data exhibiting a relatively linear trend, find the line of best fit, plot the data and the line, interpret the slope, and use the linear equation to make a prediction. Also, find r² (coefficient of determination) and r (correlation coefficient). Discuss your findings. Your topic may be that is related to sports, your work, a hobby, or something you find interesting. If you choose, you may use the suggestions described below.

A Linear Model Example and Technology Tips are provided in separate documents.

Tasks for Linear Regression Model (LR)

(LR-1) Describe your topic, provide your data, and cite your source. Collect at least 8 data points. Label appropriately.  (Highly recommended: Post this information in the Linear Model Project discussion as well as in your completed project. Include a brief informative description in the title of your posting. Each student must use different data.)

The idea with the discussion posting is two-fold: (1) To share your interesting project idea with your classmates, and (2) To give me a chance to give you a brief thumbs-up or thumbs-down about your proposed topic and data. Sometimes students get off on the wrong foot or misunderstand the intent of the project, and your posting provides an opportunity for some feedback. Remark: Students may choose similar topics, but must have different data sets. For example, several students may be interested in a particular Olympic sport, and that is fine, but they must collect different data, perhaps from different events or different gender.

(LR-2) Plot the points (x, y) to obtain a scatterplot. Use an appropriate scale on the horizontal and vertical axes and be sure to label carefully. Visually judge whether the data points exhibit a relatively linear trend. (If so, proceed. If not, try a different topic or data set.)

(LR-3) Find the line of best fit (regression line) and graph it on the scatterplot. State the equation of the line.

(LR-4) State the slope of the line of best fit. Carefully interpret the meaning of the slope in a sentence or two.

(LR-5) Find and state the value of r², the coefficient of determination, and r, the correlation coefficient. Discuss your findings in a few sentences. Is r positive or negative? Why? Is a line a good curve to fit to this data? Why or why not? Is the linear relationship very strong, moderately strong, weak, or nonexistent?

(LR-6) Choose a value of interest and use the line of best fit to make an estimate or prediction. Show calculation work.

(LR-7) Write a brief narrative of a paragraph or two. Summarize your findings and be sure to mention any aspect of the linear model project (topic, data, scatterplot, line, r, or estimate, etc.) that you found particularly important or interesting.

You may submit all of your project in one document or a combination of documents, which may consist of word processing documents or spreadsheets or scanned handwritten work, provided it is clearly labeled where each task can be found. Be sure to include your name. Projects are graded on the basis of completeness, correctness, ease in locating all of the checklist items, and strength of the narrative portions.

A psychologist conducted an experiment analysing the relationship between student scores in an exam and the amount of attention they paid in class. The latter was measured using a type of brain monitor. The Psychologist believed that scores would increase by 1 for every two unit increase in attention. The data are listed in the excel spreadsheet.

Estimate a linear regression between the score (Y) and the measure of attention(X).

(a) Write out the equation for Y in the form , but with coefficients. Show the estimated standard errors in parenthesis below the coefficients. What is the R2 of the regression? Calculate a 99 percent confidence interval for β.                                                               [5 pts]

(b) What are the mean and the estimated standard deviation of the estimated residuals? [2 pts]

Hint: the first answer is definitional and the second answer is easily seen from the output.

(c )Test the hypothesis that there is no relationship between the variables at the 90 percent significance level.                                                                                                    [3 pts]

(d) Test the hypothesis that the coefficient β=0.5 at the 99% significance level.               [3 pts]

(e) The Psychologist concluded from the experiment that test scores increase significantly if students pay attention in class. In one word, how would you describe the results of this experiment based on the data you have?                                                                                                       [2 pts]

Question 3

Amritha Singh is a middle manager with Coaster Plus Ltd (Coasters), a company that designs and manufactures roller coasters for amusement parks across North America. She has been appointed one of the project managers for the design and delivery of a special roller coaster for the Ultimate Park Ltd, an American customer. A major component of the project is the steel tracking, and one possible source is Trackers Canada Ltd (Trackers). Amritha’s supervisor has asked her to negotiate the necessary contract. Amritha began negotiations with Jason Hughes. Jason is a representative of Trackers, the steel tracking manufacturer willing to supply tracking to Coasters, Amritha’s employer. Amritha provided Jason with the plans and specifications for the roller coaster, and they negotiated a number of points, including price, delivery dates, and tracking quality. A short time later, Jason offered to sell Coasters a total of 900 metres of track in accordance with the plans and specifications provided. Jason’s offer contained, among other matter, the purchase price ($1.5 million), delivery date, terms of payment, insurance obligations concerning the track, and a series of warranties related to the quality and performance of the tracking to be supplied. There was also a clause, inserted at Amritha’s express request, which required Trackers to pay $5000 to Coasters for every day it was late in delivering the tracking.

After renewing the offer several days, Amritha for several days, Amritha contacted Jason and said, “You drive a hard bargain, and there are aspects of your offer that I’m not entirely happy with. However, I accept your offer on behalf of my company. I’m looking forward to doing business with you.”

Within a month, Trackers faced a 20% increase in manufacturing costs owing to an unexpected shortage in steel. Jason contacted Amritha to explain this development and worried aloud that without an agreement from Coasters to pay 20% more for the tracking, Trackers would be unable to make its delivery date. Amritha received instructions from her supervisor to agree to the increased purchase price in order to ensure timely delivery. Amritha communicated this news to Jason, who thanked her profusely for being so cooperative and understanding.

Jason kept his word and the tracking was delivered on time. However, Coasters has now determined that its profit margin on the American deal is lower than expected, and it is looking for ways to cut costs Amritha is told by her boss to let Jason know that Coasters will not be paying the 20% price increase and will remit payment only in the amount set out in the contract. Jason and Trackers are stunned by this development.

Applying the relevant principle(s) of contract law discuss the following questions:

a) Whether the negotiations between Jason and Amritha have legal consequences. (3 marks)

b) Discuss specific applicable ways by which each party mentioned above could have avoided the contract and as well as the implications of each way identified. (4 marks)

c) Discuss the consequences of the instruction of Amritha’s boss to the effect that Coasters will not be paying the 20% price increase and will remit payment only in the amount set out in the contract. (4 marks)

Objectives:

        The objectives of this lab exercise are to:

1. Demonstrate an understanding of the concept of operator precedence in Python expressions and statements.
2. Take simple problem descriptions and produce small but complete Python programs that solve these problems.
3. Give you some practice in using simple Python interactive input and output capabilities.
4. Give you some practice in the simplest Python decision statement (if).
5. Give you some practice in the simplest Python loop statement (while).

Specifications:

This is a four-part exercise.

1. For the three assignment statements listed below, label the operators according to the order they will be evaluated, i.e., label the first evaluated operator with a 1, the second with a 2, and so on.   Then fill in the blank with the result assigned to variable x in each part.

                        i.    x = 7 + 3 * 6 / 2 – 1                                                                                                                       

                                 x = ________

                        ii.   x = 2 % 2 + 2 * 2 – 2 / 2                                                                                                                            

                                 x = ________

                        iii.   x = ( 3 * 9 * ( 3 + ( 9 * 3 / 3 ) ) )                                                                                                    

                                 x = ________

2. Write a Python program that inputs three (3) integers to IDLE from the keyboard and prints the sum, average, product, smallest and largest of these numbers. For this exercise you may assume the user does NOT enter any duplicate values. The interactive screen dialogue should look something like this (user input is shown in bold):

Input three different integers separated by <enters>:

13

27

14

                                    Sum is 54

                                    Average is 18

                                    Product is 4914

                                    Smallest is 13

                                    Largest is 27

3. Write a Python program in IDLE that asks for the radius of a circle and prints the circle’s diameter, circumference, and area. Import the math library for p. Do the calculations for diameter, circumference and area in the output statements. You do NOT need variables for holding your calculated values of diameter, circumference, or area. Just place the appropriate expression as an argument to the print() function.

4. Write a Python program in IDLE that asks for an integer and determines and prints whether it is odd or even. (Hint: Use the modulus operator (%). An even number is a multiple of 2 and any multiple of 2 leaves a remainder of zero (0) when divided by 2).

Discussion:

In addition to the documentation requirements specified in lab 1, first write the entire program in pseudocode as comments. When necessary place a comment to the right of complicated lines to clarify your code to the reader. Further, comments should not merely repeat what is obvious from a program statement. For example, avoid what follows. This statement below adds nothing to understanding what the statement does or what its purpose is within the program:

                        Sum = Sum + 1   # Add 1 to Sum ß A totally worthless comment!

Deliverable(s):

Your deliverable should be a Word document with screenshots showing the sample code you have created, and discuss the issues that you had for this project related to AWS and/or Python IDE and how you solved them.

Turn in your source code listings for the programs developed above. Include screen shots of the results from running the programs you developed for three (3) sets of test data (for each program). Choose your test cases carefully so they reflect good values to test all aspects of your solutions.
