As an effective speaker the key element we are taught is to "Know (analyze) your audience". After reviewing this chapter what have you learned are other important elements that you must do (know) when planning a presentation? How many main points should a speaker include in their presentation/speech? Open a dialogue to discuss the effectiveness and ineffectiveness of a speaker's use of humor in presentations/speeches (Respond in agreement or disagreement to other virtual classmates post(s).

Types of Delivery

The word presentation may conjure up images of a speaker standing behind a lectern delivering information to a passive audience. While some business and professional presentations certainly follow this model, many of them are far more interactive.

There are three presentation styles: monologues, guided discussions, and interactive presentations.¹

Monologues are speeches delivered without interruption or audience involvement. An example might be when the presenter of an award introduces the winner to the audience by sharing some kind remarks about that person’s achievements. Monologues are most appropriate in large settings and on formal occasions. In smaller groups, they can feel artificial and create the impression the speaker does not care much about the audience.

Guided discussions are more interactive. In this type of presentation, a speaker provides information and has a preset idea of which material will be covered, but listeners are encouraged to speak up with questions and comments. Managing a guided discussion is more challenging, but the potential for more audience buy-in can be worth the effort.

Interactive presentations, as their name implies, involve the audience even more. Although the speaker still controls the program, an interactive presentation feels more like a conversation than a speech. Interactive presentations are common in sales settings, where customer interest drives the communication.

Speakers have four options when delivering presentations: manuscript, memorized, extemporaneous, 325and impromptu. However, two of them—extemporaneous and impromptu—will serve you best in most situations.

Once you have the dataset, please use knowledge gained in other business and/or economics classes to realize what topic and theory the data could relate and a research question that it could allow you to answer. More specifically, please put together an analysis by making sure your project report includes the following:

1. Brief statement of the research topic and problem. As you get the dataset from me, you would need to use some imagination what research problem that data could be related to. Nevertheless, please state very briefly (i.e. in one paragraph) what theory (research literature or textbooks related to business or economics) says about the research problem – e.g. is there some dilemma or controversy that your research will help to clarify.
2. Clearly worded research question that limits the research problem to researchable task. (This is a short sentence that ends with the question mark and it is suggested that you draw from theory (research literature / textbook knowledge) in one of the business studies field to word it!)
3. Please identify the type of data that you are working with – on what type of measurement scale(s) where the selected variables measured by the original data collectors. (As you work with the dataset given by me, use your educated guess).
4. Describe the data with the tools of descriptive statistics, using both numerical as well as graphical methods. In addition to reporting and commenting on the values central tendency and diagrams, please also justify the choice of method (e.g. why a particular kind of measure of central tendency was selected and the chosen graphic is appropriate to use in this context).
5. Justify the selection of the specific data analysis method of inferential statistics. Recommendation – use the decision tree (introduced in Ch. 9ff) to make the selection and justification of it. You should look up also the assumptions and comment how your data meets them but I will not penalize you if it does not meet all the criteria. Nevertheless, please make sure that you include the basic information about distribution of the variables – are they more or less normally distributed (use both numerical as well as graphical methods). It is required that you restrict the choice of data analysis method(s) to the ones introduced in the class. (In addition to the fact that we covered only the most basic / frequently used methods in class, also the spreadsheet program (Excel) which the textbook is based on and that I presented during the course, has limited set of methods available).
6. Formulate the null and research (alternative) hypothesis – similarly to point 2 it is recommended that you word them on the basis of research literature / textbook knowledge in one of the business studies field that you know);
7. Determine the test criteria:

7.1. Specify the level of significance (Type I error associated with the null hypothesis),

7.2. Determine the test statistic (the appropriate statistical test as mentioned under point 5 above),

7.3. Determine the critical values (and region(s) if applicable),

8. Calculate the value of the test statistic (obtained value).
9. Make a decision about the null and research hypothesis by comparing the obtained value to the critical value and interpret the results of the data. You can pay attention also to the p-values.
10. Sum up you research report by relating the statistical test result(s) to the research question and theory that you set to test.

Common CSS Concepts

1) [True or False] By default, backgrounds extend all the way to the inside edge of the element’s border.

2) [True or False] By default, backgrounds are transparent.

3) [Critical Thinking] Why does the author choose to hide the text of his heading tags from visible view while showing an image instead?

4) The CSS color property is used to define the color for the content of the element. In the case of a p tag (paragraph) what will this property effect?

5) [True or False] Absolute values are good for devices in which the exact size is already known, for example a printer.

6) [True or False] An advantage to using the relative value em is that the starting size of the text is up to the device itself. As the user changes the resolution, the relationship of the sizes based on ems will stay exactly the same.

7) [True or False] Pixels are calculated relative to the parent element.

8) [True or False] According to our author normal document flow can and should handle the majority of our layout needs.

9) Which value of the position property removes an element from normal document flow and repositions the element based on top, right, left or bottom offset values?

10) [True or False] To determine its position, an absolutely positioned element looks to the nearest parent element that has positioning. If no elements are positioned above it, it looks to the body tag for positioning.

11) [True or False] Fixed positioning is similar to absolute, but the position is always relative to the active viewport, not the parent element.

12) Which CSS property controls allow positioned elements to stack (appear on top of) other elements?

13) [True or False] When we float an element, it moves as far over as it can, either to the right or to the left, and the elements below it move up to take up the space the floated element used to occupy.

14) [True or False] When we float an element, we essentially remove it from normal document flow.

15) [Critical Thinking] If we wish the text in a paragraph tag to wrap to the left on a floated image, what value do we set to the float property of the image?

16) Which flexbox child property places child elements one on top of each other? (vertically)

17) While the grid layout is a powerful tool, it may not be fully supported by all browsers at this time. The author mentioned a couple of tactics to use grids with browsers that don’t fully support grids at this time. Name 1.

18) According to the author, what is an advantage of using lots of comments in our CSS?

19) [Critical Thinking] What is an advantage of grouping related styles in the same place?

20) According to the author, why should we consider splitting our CSS into multiple files?

21) What does the author do to inspect an element on a page?

22) What does a code linter do?

Introduction to responsive web design - 2:40

23) [Critical Thinking] In the video the author flexes the screen to approximate what the page would look like on a mobile phone. Would this be sufficient to determine how a the page would work for a phone? If not, why not?

24) [Critical Thinking] Write the exact syntax of a media query that allows you to write styles for all screens smaller than 600 pixels.

25) What does the author mean by mobile first?

CSS frameworks and grids - 1:23

26) [Critical Thinking] When should we consider using a CSS framework instead of creating our own CSS?

27) According to the author, what is the biggest reason to use CSS pre-processors?

Scenario

Frank has only had a brief introduction to statistics when he was in high school 12 years ago, and that did not cover inferential statistics. He is not confident in his ability to answer some of the problems posed in the course.

As Frank's tutor, you need to provide Frank with guidance and instruction on a worksheet he has partially filled out. Your job is to help him understand and comprehend the material. You should not simply be providing him with an answer as this will not help when it comes time to take the test. Instead, you will be providing a step-by-step breakdown of the problems including an explanation on why you did each step and using proper terminology.

What to Submit

To complete this assignment, you must first download the word document, and then complete it by including the following items on the worksheet:

Incorrect Answers

Correct any wrong answers. You must also explain the error performed in the problem in your own words.

Partially Finished Work

Complete any partially completed work. Make sure to provide step-by-step instructions including explanations.

Blank Questions

Your step-by-step breakdown of the problems, including explanations, should be present within the word document provided. You must also include an Excel workbook which shows all your calculations performed.

WORKSHEET:

Deliverable 02 – Worksheet

Instructions: The following worksheet is shown to you by a student who is asking for help. Your job is to help the student walk through the problems by showing the student how to solve each problem in detail. You are expected to explain all of the steps in your own words.

Key:

<i> - This problem is an incorrect. Your job is to find the errors, correct the errors, and explain what they did wrong.

<p> - This problem is partially finished. You must complete the problem by showing all steps while explaining yourself.

<b> - This problem is blank. You must start from scratch and explain how you will approach the problem, how you solve it, and explain why you took each step.

<p> Assume that a randomly selected subject is given a bone density test. Those tests follow a standard normal distribution. Find the probability that the bone density score for this subject is between -1.53 and 1.98

Student’s answer: We first need to find the probability for each of these z-scores using Excel.

For -1.53 the probability from the left is 0.0630, and for 1.98 the probability from the left is 0.9761.

Continue the solution:

<b> The U.S. Airforce requires that pilots have a height between 64 in. and 77 in. If women’s heights are normally distributed with a mean of 65 in. and a standard deviation of 3.5 in, find the percentage of women that meet the height requirement.

Answer and Explanation:

<i> Women’s pulse rates are normally distributed with a mean of 69.4 beats per minute and a standard deviation of 11.3 beats per minute. What is the z-score for a woman having a pulse rate of 66 beats per minute?

Student’s answer:

Let

            Corrections:

<b> What is the cumulative area from the left under the curve for a z-score of -0.875? What is the area on the right of that z-score?

Answer and Explanation:

<i> If the area under the standard normal distribution curve is 0.6573 from the right, what is the corresponding z-score?

Student’s answer: We plug in “=NORM.INV(0.6573, 0, 1)” into Excel and get a z-score of 0.41.

Corrections:

<p> Manhole covers must be a minimum of 22 in. in diameter, but can be as much as 60 in. Men have shoulder widths that are normally distributed with a mean of 18.2 and a standard deviation of 2.09 in. Assume that a manhole cover is constructed with a diameter of 22.5 in. What percentage of men will fit into a manhole with this diameter?

Student’s answer: We need to find the probability that men will fit into the manhole. The first step is to find the probability that the men’s shoulder is less than 22.5 inches.

Deliverables

There is one deliverable for this assignment

• hw6.py

Make sure the script obeys all the rules in the Script Requirements page.

Specification

The script must have 3 functions:

• get_args
• create_python_file
• print_directory

get_args

This function must have the following header:

def get_args(arg_number):

This function takes as its parameter an integer.

The function should look at the number of command line arguments that the script gets when it is run.

If the number of command line arguments is less than the parameter, it should print a usage message in the form specified in the Class Notes and the function should cause the script to quit.

If it gets the right number of command line arguments it should return those arguments.

Remember that the length of sys.argv is always one more than the number of command line arguments.

The test code will use the first command line argument as the argument to create_python_file and the second command line argument as the argument to print_directory.

create_python_file

This function must have the following header:

def create_python_file(filename):

This function takes as it's parameter a name of a Python script without the .py extension.

The first thing the function should do is check that there is no . (dot) in the filename.

If there is, the function should print an error message and the script should quit.

This error message must contain the word "ERROR".

Otherwise the function should add ".py" to the filename.

It should then use the Unix command touch to create a file with that filename.

touch when run with an argument creates a file of that name.

Then the function should give this file 755 permissions using the Unix chmod command.

print_directory

This function must have the following header:

def print_directory(path):

This function takes as it's parameter a path.

The first thing that the function should do is check to make sure the path is a directory that exits.

If the directory does not exist the function should print an error message and quit.

This error message must contain the word "ERROR".

Otherwise, the function should print the entries in the directory specified by the path parameter.

Script for this assignment

Open an a text editor and create the file hw6.py.

You can use the editor built into IDLE or a program like Sublime.

Test Code

Your hw6.py file must contain the following test code at the bottom of the file:

filename, path = get_args(2)
print(filename, path)
create_python_file(filename)
print_directory(path)

Suggestions

Write this program in a step-by-step fashion using the technique of incremental development.

In other words, write a bit of code, test it, make whatever changes you need to get it working, and go on to the next step.

1. Create the file hw5.py.
   Write a statement to import the os and sys modules.
   Enter the headers for get_args, create_python_file and print_directory.
   Under each header write the Python statement pass.
   Run the script.
   Fix any errors you find.
2. Remove the pass statement from get_args.
   Replace it with an if statement that prints an error message if the length of sys.argv is less the value of the parameter arg_number plus 1.
   After the print statement, but still inside the if statement, write at statement that causes the script to quit. Copy the first line of the test code into your script at the bottom of the file.
   Run the script with no arguments.
   You should see the error message,
   Run the script with one argument.
   You should see the error message.
   Run the script with two arguments.
   You should not see your error message, but you will get a TypeError.
   Fix any errors you find.
3. Outside the if statement write a return statement that that returns the first two elements in sys.argv.
   Copy the second line of the test code into your script at the bottom of the file.
   Run the script with two arguments.
   You should see those two arguments.
   Fix any errors you find.
4. Replace the text in the print statement with the text of a usage message as described in Class Notes 10.
   Your message should have the same format as shown in the Class Notes and it should print only the name of the script, with no path. Run the script with no arguments.
   You should see

   Usage: hw6.py FILENAME PATH

   Fix any error you find.
5. Remove the pass statement from create_python_file.
   In it place write an if statement which prints an error message if the argument

The Protek Company is a large manufacturer and distributor of electronic components. Because of some successful new products marketed to manufacturers of personal computers, the firm has recently undergone a period of explosive growth, more than doubling its revenues during the last two years. However, the growth has been accompanied by a marked decline in profitability and a precipitous drop in the company’s stock price.

You are a financial consultant who has been retained to analyze the company’s performance and find out what’s going wrong. Your investigative plan involves a series of in-depth interviews with management and doing some independent research on the industry. However, before starting, you want to focus your thinking to be sure you can ask the right questions. You’ll begin by analyzing the firm’s financials over the last three years, which are presented in the supplemental datasheet. Assume the company sold no property, plant, or equipment during the time periods presented. Also assume the company did not repay any long-term debt. The company’s normal credit terms extended to its customers is net 30.

Complete the following using Microsoft Excel and Word. All quantitative analysis should be done in Excel, while all qualitative analysis should be completed in Word. Construct horizontal analysis (year-over-year growth) on the financial statements for 2019 and 2020. Analyze the trend in each line; what does the trend analysis reveal? What are strengths, and areas for concern? Construct common size balance sheets for 2018 - 2020, respectively, and common size income statements for 2018 - 2020, respectively. Analyze the trend in each line. What appears to be happening? What are your significant findings? Construct Statements of Cash Flows for 2019 and 2020 using the indirect method. Also compute Free Cash Flow for each year. Where is the company’s cash going to and coming from? What are strengths, and areas for concern? Calculate all the financial ratios discussed in chapter 15 (use exhibit 15-6 as a guide) for 2019 and 2020. Analyze trends in each ratio. What can you infer from this information? Make specific statements about liquidity, asset management, debt management, profitability, and market performance. Do not simply say that ratios are higher or lower (or that they are going up or down); instead, think about what might be going on in the company and propose reasons why the ratios are acting as they are. Finally, based on all of your analysis, what two (or more) specific actionable items should the company do to improve its situation? Be specific in your response and discuss the implication of your recommendation.
