"A study was conducted to evaluate new test for human papilloma virus (HPV). One hundred fifteen women with HPV were compared to 426 women who did not have HPV. A total of 97 women tested positive using the new test, 81 of whom really did have HPV.

You will be graded on calculations (including completion of the 2x2 table as shown in class and showing your work for calculation, your interpretations, and your answers to the other questions. Your interpretations must be specific and will be graded on accuracy, correct use of scientific terminology, professional writing style, grammar and spelling."

c) Calculate and interpret the sensitivity of the new screening test.

d) Calculate and interpret the specificity of the new screening test.

e) Calculate and interpret the positive predictive value of the new screening test.

f) Calculate and interpret the negative predictive value of the new screening test.

g) Do you think that it would be better to use this new screening test for HPV or an older screening test with 90% sensitivity and 80% specificity. The older screening test is more expensive. Write 75-100 words supporting your position.

Rocky Road Bikes is evaluating the possibility of offering a new top-of-the-line bike model. The company’s market research team estimates that first year sales of the new model will be 25,000 units at the proposed price of $750.00 per unit and estimated cost per unit of $275.00. Sales are expected to grow 4% per year in each of the following 5 years, until the new model is discontinued at the end of year 6. The market research team also estimates the introduction of the new model will erode sales of the current top model by a constant 5,000 units per year. The current top model has a price of $500.00 and associated costs of $145.00.The required tooling and machinery to manufacture the new model will cost a total of $15,000,000, and this will be depreciated on a straight-line basis over the six-year life of the project to zero. The company expects to be able to sell the machinery at the end of the project for $3,000,000. There will also be fixed costs associated with the new model of $6,000,000 per year. The new model will require an increase in working capital of $250,000 which will be returned at the end of the project. Rocky Road has a tax rate of 35%, and management believes that the discount rate for this project should be 12%.

Tanya Williams is the new accounts manager at Southpac Bank. She has just been asked to estimate how many new bank accounts she will generate during the next year. The Australian economy has been growing and the bank has experienced a 10 percent increase in the number of bank accounts over each of the past five years. In the year just ended the bank had 10000 accounts.

The new accounts manager is paid a salary plus a bonus of $50 for every new account she generates above the budgeted amount. Thus, if the annual budget calls for 500 new accounts and 540 new accounts are achieved, Williams’ bonus will be $2 000 (40 × $50). Williams believes that the economy will continue to grow at the same rate next year as it has in recent years. She has decided to submit a budgetary projection of 700 new accounts for the coming year.

Required:

1)Your consulting firm has been hired by the managing director of the bank to make recommendations for improving its operations. Define and explain the negative consequences of budgetary slack.

2)Discuss how the bonus program may encourage budgetary slack.

3)How might the bank reduce the incentive to create budgetary slack?

Firm A, under Chapter 11 bankruptcy proceedings, has an estimated going-concern reorganization value of $3.0 million. The last pre-bankruptcy balance sheet of the firm is below (this shows the “old” capital structure). Assume that there are no other claims from any party.

LAST PRE-BANKRUPTCY BALANCE SHEET

ASSETS

Current Assets                                             $1,250,000   

Fixed Assets                                                  3,500,000    

TOTAL ASSETS                                          $4,750,000

LIABILITIES and NET WORTH

Senior Debt                                                    1,000,000

Subordinated Debt                                         3,000,000

Common Stockholders Equity    750,000   

TOTAL LIABILITIES and NET WORTH   $4,750,000

Assume that the reorganized “new” capital structure must be 2/3 debt and 1/3 common equity, with $1,500,000 of the new debt subordinated to senior debt. After the fair distribution of the new securities under the reorganization:

a.

the “old” Senior Debt of $1,000,000 in the last pre-bankruptcy balance sheet will after the reorganization end up with “new” Senior Debt of $1,000,000.

b.

The “old” Common Stockholders Equity of $750,000 in the last pre-bankruptcy balance sheet will after the reorganization end up with “new” Common Stockholders Equity of $750,000.

c.

The “old” Subordinated Debt of $3,000,000 in the last pre-bankruptcy balance sheet will after the reorganization end up with “new” Subordinated Debt of $1,000,000, and “new” Common Stockholders Equity of $1,000,000.

Northwood Company manufactures basketballs. The company has a ball that sells for $25. At present, the ball is manufactured in a small plant that relies heavily on direct labor workers. Thus, variable expenses are high, totaling $15.00 per ball, of which 60% is direct labor cost.

Last year, the company sold 32,000 of these balls, with the following results:

5. Refer to the original data. The company is discussing the construction of a new, automated manufacturing plant. The new plant would slash variable expenses per ball by 40.00%, but it would cause fixed expenses per year to double. If the new plant is built, what would be the company’s new CM ratio and new break-even point in balls?

6. Refer to the data in (5) above.

a. If the new plant is built, how many balls will have to be sold next year to earn the same net operating income, $109,000, as last year?

b. Assume the new plant is built and that next year the company manufactures and sells 32,000 balls (the same number as sold last year). Prepare a contribution format income statement and compute the degree of operating leverage.

A new blood clotting drug has been developed and researcher are interested to see if the new drug out performs the most commonly used treatment. 6 patients were given the new drug and 7 patients were given the old drug. The clotting times were recorded (lower times are better). The data are:

1: What is the null hypothesis?

a: there is no difference in clotting times

b: the old drug clots faster

c: the new drug clots faster

d: there is a difference in clotting times

2: What is the value of the test statistic?

3: How many degrees of freedom are there?

4: What we conclude if we ran a two tailed test?

a: there is no evidence of a difference in clotting times

b: there is evidence that the new drug results in faster clotting

c: there is evidence that the old drug results in faster clotting

5: What would we conclude if we had instead used a one-tailed test?

a: there is no evidence of a difference in clotting times

b: there is evidence that the new drug results in faster clotting

c: there is evidence that the old drug results in faster clotting
