Bernard Associates conducted a survey in March 2004 of 1021 workers who held white-collar jobs and had changed jobs in the previous twelve months. Of these workers, 46% of the men and 37% of the women were paid more for their positions when they changed jobs. Suppose that these percentages are based on random samples of 510 mean 511 woman white-collar workers.

Construct a 95% confidence interval for the difference between the two population proportions.

Using a 1% significance level can you conclude that the two populations are different?

A nonprofit company concerned with the school dropout rates has designed a tutoring program aimed at students between 16 to 18 years old. A national center for educational statistics reported that the high school dropout rate for the year 2000 was 10.9​%. One school​ district, who adopted the use of the​ nonprofit's tutoring program and whose dropout rate has always been very close to the national​ average, reported in 2004 that 183 of their 1772 students dropped out. Is their experience evidence that the tutoring program has been​ effective?

The following question presents hypothetical data concerning transfer of cotton between departments as part of the Cotton On Group's production processes. The textile department produces cotton for use by various other production departments within the Cotton On Group. The costs incurred by the textile department to produce cotton are provided below:

The textile department can also sell cotton to external customers for $5.00 per square metre. Sales staff from the textile department are paid a sales commission of $0.10 per square metre for sales to external customers. No sales commissions are paid for transfers to internal customers.

Required

1. Provide and discuss three examples which illustrate how cost-plus pricing could be used to set the internal transfer price for cotton and how these prices impact departmental profitability.

Do hypothesis testing (t test)

Test to see if there is a difference between grade of male and female students - insert the SPSS output in the space below.

a- What would be the alternate hypothesis for the study?                                                

b- What would be the null hypothesis?                                                         

c- What Level of Significance do you choose?                                              

d- What is the computed t critical value for the study?                                

e- What is the P-value of the test?                  

f- What is the conclusion?

Please show steps in the calculation.

1. There are three kinds of apple sold in a supermarket, namely Red Delicious, Fuji and Ambrosia. By experience, the chance of a customer purchases Fuji three times as much as each of the other two kinds. Suppose, there are 10 unrelated customers going to buy an apple and the supermarket management is interested in studying the sales of Fuji.

Answer the following: (Hint: Binomial distribution)

1. Show this is a Binomial experiment by stating the requirement in the context.

2. What is the chance that 7 customers will buy Fuji?

3. What is the chance that 3 customers will not buy Fuji?

4. What is the chance that at most 8 customers will buy Fuji?

5. For these 10 customers, how many does the management expect to buy Fuji on the average?

Starcups Coffee Company is launching a new sustainability initiative that would reward customers for purchasing a reusable cup. During the cup promotion, customers would pay an extra $1.00 for the reusable cup and would receive a 20% discount each time they return with the cup to buy a cup of coffee.

Each week Starcups serves 41,000 customers who purchase an average of 2.00 cups of coffee per week (82,000 cups total). Starcups’s contribution margin income statement for a typical week is shown below:

Assume the new cup promotion is expected to impact sales volume, revenue, fixed, and variable costs as follows:

• Starcups estimates that 25% of its current customers (10,250) will participate in the promotion. The remainder of its existing customer base (30,750) will continue to buy an average of 2.00 cups of coffee per week.
• Starcups expected to attract 5,100 new customers to participate in the promotion.
• Customers who participate in the promotion will pay an additional $1.00 for the reusable cup. They will then receive a 20% discount on repeat visits when they bring back their reusable cup.
• The additional variable cost of purchasing the reusable cup is $1.60. The variable cost savings of the paper cup is $.30.
• Starcups expects that customers who participate in the reusable cup promotion will visit an average of 5 times per week, including the first purchase of the reusable cup.
• Starcups will spend a total of $11,000 per week advertising the reusable cup promotion.

Required:
1. Prepare a contribution margin income statement to predict how the reusable cup promotion will impact weekly net operating income.



2. Compute the difference in total revenue, total variable costs, total contribution margin, total fixed costs, and total operating income before and after the promotion.

What is the difference between gain and revenue? Are they reported differently on the income statement?

Discuss how to distinguish between the accounting for capital expenditures and revenue expenditures.
