A colleague of yours from the GIMPA School of Technology has decided to venture into Sobolo production and as a student of Managerial Economics, he/she has pleaded with you to help boost demand and revenue. You estimated that the demand equation for his or her Sobolo is: ??=50−0.5??+0.2?+0.5???+1.25? where Qs is the number of 500ml bottles of Sobolo demanded, Ps is the price he/she charges per 500ml bottle of Sobolo, I is the average income per month of his or her customers and Pos is the price his or her closest competitors charge per 500ml bottle of Sobolo and A is your colleague’s investment in marketing or advertisement campaign: a) Interpret the demand equation and explain what might have informed your choice of these factors as key determinants of Sobolo demand and why? b) Suppose that your colleague sold 350 bottles of Sobolo last week, where I = GHc 1,500, Pos = GHc 2.00 with no investment in advertisement, what is the price (Ps) that your colleague charged per bottle of Sobolo? Find and explain the price and income elasticities of demand for Sobolo. c) Your colleague is considering a GHc 1,100 promotional campaign to bolster sales and revenues and you have projected that the promotional campaign will change the demand equation to: ??=55−0.5??+0.2?+0.5???+4.25? Supposing that your projections are accurate, what number of bottles of Sobolo (Qs) will your colleague sell and why based on ?? , ? and ??? info in b? d) How will the concept of opportunity cost help you establish whether your colleague’s promotional campaign will be effective or not given no change in average income of his or her customers and no change in price of his or her closest competitors? What is advertisement elasticity of demand for Sobolo?

Jenna is an active teenager involved in sports at school and loves playing with her older brothers. Jenna’s mother has noticed that her daughter easily bruises during her activities. Jenna also has had frequent nose bleeds from a young age and has heavy menstrual periods that last longer than usual. Her mother recognizes these symptoms because she has lived with them too. In fact, she remembers Jenna’s grandmother telling her they come from a family of ‘bleeders’.

a. What do these symptoms mean regarding their blood?

b. Would this be a case of hemophilia? Why or why not?

c. What possible condition might they have?

The school district recently adopted the use of e-textbooks, and the superintendent is interested in determining the level of satisfaction with e-textbooks among students and if there is a relationship between the level of satisfaction and student classification. The superintendent selected a sample of students from one high school and asked them how satisfied they were with the use of e-textbooks. The data that were collected are presented in the following table.

Table 1: Student Classification (N=128)

Questions

1. Of the students that were satisfied, what percent were Freshmen, Sophomore, Junior, and Senior? (Round your final answer to 1 decimal place).

2. State an appropriate null hypothesis for this analysis.

3. What is the value of the chi-square statistic?

4. What are the reported degrees of freedom?

5. What is the reported level of significance?

6. Based on the results of the chi-square test of independence, is there an association between e-textbook satisfaction and academic classification?

7. Present the results as they might appear in an article.

This must include a table and narrative statement that reports and interprets the results of the analysis. Note: The table must be created using your word processing program. Tables that are copied and pasted from SPSS are not acceptable.

A sample of 8 children in the 5th grade of North Stratfield School run the 100 meter dash in a average time of 20.2 seconds. Assume the bias adjusted sample standard deviation of the individual 100 meter dash times is 7.1 seconds.
Construct a 99% confidence interval for μ, the true population mean 100 meter dash time. Since n is small, the t statistic will be used in deriving this confidence interval.
What is the degrees of freedom parameter that should be used to derive the t-value?

The scores of students on the SAT college entrance examinations at a certain high school had a normal distribution with mean μ=542.7 and standard deviation σ=29.8.

(a) What is the probability that a single student randomly chosen from all those taking the test scores 546 or higher?

(b) What are the mean and standard deviation of the sample mean score x¯, of 35 students?
The mean of the sampling distribution for x¯is:  
The standard deviation of the sampling distribution for x¯ is:

(c) What z-score corresponds to the mean score x¯ of 546?
ANSWER:

(d) What is the probability that the mean score x¯ of these students is 546 or higher?
ANSWER:  

A random sample of 75 pre-school children was taken. The child was asked to draw a nickel. The diameter of that nickel was recorded. Their parent's incomes (in thousands of $) and the diameter of the nickel they drew are given below.

Test the claim that there is significant correlation at the 0.01 significance level. Retain at least 3 decimals on all values.

a) Identify the correct alternative hypothesis.

• H1:ρ=0H1:ρ=0
• H1:r≠0H1:r≠0
• H1:μ≠0H1:μ≠0
• H1:pL≠pHH1:pL≠pH
• H1:ρ≠0H1:ρ≠0

b) The rr test statistic value is:   

c) The critical value is:

d) Based on this, we

• Reject H0H0
• Fail to reject H0H0

e) Which means

• There is sufficient evidence to warrant rejection of the claim
• There is not sufficient evidence to support the claim
• The sample data supports the claim
• There is not sufficient evidence to warrant rejection of the claim

f) The regression equation (in terms of income xx) is:
ˆy=y^=   

g) To predict what diameter a child would draw a nickel given family income, it would be most appropriate to:

• Use the regression equation
• Use the mean coin size
• Use the P-Value
• Use the residual

Part a VenRam Stationery & Supplies sells a variety of school supplies including a variety of calculators. The business began the first quarter (January to March) of 2018 with 20 (Casio fx-85MS) calculators at a total cost of $124,800. During the quarter, the company completed the following transactions. January 8 105 calculators were purchased at a cost of $5,840 each. In addition the business paid a freight charge of $610 cash on each calculator to have the inventory shipped from the point of purchase to their warehouse. January 31 The sales for January were 85 calculators which yielded total sales revenue of $767,550. ( 25 of these units were sold on account to longstanding customers) February 4 A new batch of 65 calculators was purchased at a total cost of $448,500 February 10 10 of the instruments purchased on February 4 were returned to the supplier, as they were not of the model ordered. February 28 During the month 58 calculators were sold at a price of $9,660 each. March 4 A customer, to whom 9 calculators were sold during the first business day of February, returned 2 of the instruments, as they were of another brand. March 10 Owing to an increased demand, a further 118 calculators were purchased at a cost of $7,500 each; these were subject to a trade discount of 2% each. March 31 125 calculators were sold during March at a unit selling price of $10,300. March 31 An actual count of inventory was carried out which revealed that there were 28 units of that brand of merchandise in the store room. Unless otherwise stated, assume that all purchases were on account and received on the dates stated. Required: i) Prepare a perpetual inventory record for this merchandise, using the first in, first out (FIFO) method of inventory valuation to determine the company’s cost of goods sold for the quarter and the value of ending. ii) Given that selling, distribution and administrative costs for the quarter were $112,840, $102,100 and $103,760 respectively, prepare an income statement for VenRam Stationery & Supplies for the quarter ended March 31, 2018. iii) Journalize the January transactions, assuming the company uses a: - Periodic inventory system - Perpetual inventory system iv) The manager of VenRam has stated that his objective is to cut back on his tax liability and is of the view that the FIFO method would be best. Do you agree with him? Part b Callahan Computers stores its inventory in a warehouse that was destroyed by Hurricane Irma in September 2018. The business began the year with inventory of $350,000. During the year, the business made net purchases of $1,600,000 and had net sales of $2,500,000. The company’s gross profit has historically been 30% of net sales revenue. Use the gross profit method to estimate the cost of the ending inventory destroyed in the hurricane.

Can you answer part (iii) of this question.

Thank you.

Here’s the scenario: You are managing a bake sale for a club at your school. It’s being held each weekend in the fall that the football team has a home game. This year, there will be five home games. The club sells cookies in packages of two dozen. The selling price per package is $9.00. The packaging material costs $.12 (12 cents) per package. You pay the regular kitchen staff a direct labor cost for mixing and baking at $10.50 per hour. Baking utensils and supplies for the entire season will cost $500 (excluding the direct costs of cookies) . Before each game, the cookies are prepared in a school kitchen for a fixed rental fee of $90 per session and clean-up labor is paid a fixed total of $60 per session. You estimate that 500 packages of cookies will be baked for each sale and that 96% of them will be sold. Alumni volunteers, who receive no compensation, sell half of the packages and students, who receive a commission of $.15 per package, sell the other half. You plan to run an advertisement in the school newspaper before all five games and each advertisement costs $200. You are to: 1) Go to the internet and find a cookie recipe. Your recipe must have at least 5 ingredients. 2) Research the prices of the cookie ingredients at a local supermarket, warehouse or online grocer. Do NOT change the recipe. To convert the recipe quantities, you can use an online conversion calculator. There are several available so use your favorite search engine. 3) Develop a budget for the five bake sales. Give the amounts per each sale and the budget in total. You are free to develop any format for the budget. I encourage you to develop a format that is most useful to you. Make sure your budget is complete in that it includes both expected income and expected expenses with a bottom line expected n et income. Use your imagination when it comes to the direct labor calculation. Your kitchen can be large and full of commercial ovens.
