Differential Analysis Report for Sales Promotion Proposal Rocket Shoe Company is planning a one-month campaign for August to promote sales of one of its two shoe products. A total of $105,000 has been budgeted for advertising, contests, redeemable coupons, and other promotional activities. The following data have been assembled for their possible usefulness in deciding which of the products to select for the campaign. Cross-Trainer Shoe Running Shoe Unit selling price $40 $44 Unit production costs: Direct materials $ (7) $(10) Direct labor (2) (3) Variable factory overhead (2) (2) Fixed factory overhead (4) (5) Total unit production costs $(15) $(20) Unit variable selling expenses (13) (12) Unit fixed selling expenses (7) (5) Total unit costs $(35) $(37) Operating income per unit $ 5 $ 7 No increase in facilities would be necessary to produce and sell the increased output. It is anticipated that 30,000 additional units of cross-trainer shoes or 25,000 additional units of running shoes could be sold without changing the unit selling price of either product. Required: 1. Prepare a differential analysis report presenting the additional revenue and additional costs anticipated from the promotion of cross-trainer shoes and running shoes.

Two used car dealerships compete side by side on a main road. The first, Harry’s Cars, always sells high-quality cars that it carefully inspects and, if necessary, services. On average, it costs Harry’s $8000 to buy and service each car that it sells. The second dealership, Lew’s Motors, always sells lower-quality cars. On average, it costs Lew’s only $5000 for each car that it sells. If consumers knew the quality of the used cars they were buying, they would pay $10,000 on average for Harry’s cars and only $7000 on average for Lew’s cars.

Without more information, consumers do not know the quality of each dealership’s cars. In this case, they would figure that they have a 50-50 chance of ending up with a high-quality car and are thus willing to pay $8500 for a car. Harry has an idea: He will offer a bumper-to-bumper warranty for all cars that he sells. He knows that a warranty lasting Y years will cost $500Y on average, and he also knows that if Lew tries to offer the same warranty, it will cost Lew $1000Y on average.

a. Suppose Harry offers a one-year warranty on all of the cars he sells. i. What is Lew’s profit if he does not offer a one-year warranty? If he does offer a one-year warranty? ii. What is Harry’s profit if Lew does not offer a one-year warranty? If he does offer a one-year warranty? iii. Will Lew’s match Harry’s one-year warranty? iv. Is it a good idea for Harry to offer a one-year warranty?

b. What if Harry offers a two-year warranty? Will this offer generate a credible signal of quality? What about a three-year warranty?

c. If you were advising Harry, how long a warranty would you urge him to offer? Explain why.

To prepare for the Week 6 Assessment, choose a well-known corporation, such as Samsung, Starbucks, Ford Motor Company, or Waste Management, that implemented a major change. Analyze the corporation’s change process based on Kotter’s 8-Step to Change using the Organizational Change Chart.

Kotter's 8-Step Change Model

• Step One: Create Urgency.
• Step Two: Form a Powerful Coalition.
• Step Three: Create a Vision for Change.
• Step Four: Communicate the Vision.
• Step Five: Remove Obstacles.
• Step Six: Create Short-Term Wins.
• Step Seven: Build on the Change.
• Step Eight: Anchor the Changes in Corporate Culture

Was this a positive organizational change? Why or why not? If so, what strategies and tactics were effective or ineffective in creating positive organizational change? What strategies and tactics would have worked better?

3. A “chord” (two or more notes played simultaneously, rather than one at a time) consists of an unordered selection (without repetition) from among the seven notes {A, B, C, D, E, F, G}.

a. How many different four note “chords” are possible?

b. How many different four note “chords” are there such that “A” is one of the four notes?

c. How many four note “chords” are there such that “A” is NOT one of the four notes?

9. TI Calculator Graded Problem Set

You are conducting a study testing whether a child’s age is a good predictor of his or her height. You have collected the following data from a random sample of seven children:

Age (months) Height (cm)

34   77

5 0   95

63   109

59   99

53   101

44    106

40    94

Perform a regression of height (dependent variable) on age (independent variable).

What is the Y-intercept of the regression line?

43.73

52.81

60.46

24.73

59.70

What is the slope (beta) of the regression line?

1.16

1.27

0.75

1.61

1.52

The regression model predicts that a 4-year-old child (48 months) would be approximately      tall.

hree percent of a man's body is essential fat; for a woman the percentage is closer to 12.5%. As the name implies, essential fat is necessary for a normal healthy body. Fat is stored in small amounts throughout the body. Too much fat, however, can be dangerous to your health. For men between 18 and 39 years old, a healthy percent of body fat ranges from 8% to 19%; for women of the same age, it's 21% to 32%. Measuring body fat can be tedious and expensive. The "standard reference" measurement is by dual-eneregy X-ray absorptiometry (DEXA), which involves two low-dose X-ray generators and takes from 10 to 20 minutes. Because of the time and expense involved with the DEXA method, health professionals would like to be able to make a useable prediction of body fat from easily measurable variables such as weight or waist size.

1) Determine the 99% confidence interval for the slope of the least squares regression line of %body fat on waist size.

2) Determine a 99% confidence interval for the mean %body fat found in people with 40-inch waists (use 2 decimal places).

3) Determine a 99% prediction interval for the %body fat of an individual with a 40-inch waist (use 2 decimal places).
