The Empire Hotel is a full-service hotel in a large city. Empire is organized into three departments that are treated as investment centers. Budget information for the coming year for these three departments is shown as follows. The managers of each of the departments are evaluated and bonuses are awarded each year based on ROI.

Required:

a. Compute the ROI for each department. Use the DuPont method to analyze the return on sales and capital turnover.

Assume the Health Spa is considering installing new exercise equipment. Upon investigating, the manager of the division finds that the equipment would cost $40,000 and that operating earnings would increase by $8,000 per year as a result of the new equipment.

b-1. What would be the ROI of investment in the new exercise equipment and Health Spa?

b-2. Would the manager of the Health Spa be motivated to undertake such an investment?

c-1. Compute the residual income for each department if the minimum required return for the Empire Hotel is 17 percent.

c-2. What would be the impact of the investment on the Health Spa's residual income?

• Which type of leadership do you prefer: Normative or Utilitarian? What does bureaucracy mean to you? Give an example of McDonaldization that has been in your life (besides the movie theater). Do you believe that McDonaldization is good, bad, or both and why?

Suppose that miles driven anually by cars in America are normally distributed with mean = 12; 894 miles and standard deviation = 1190 miles.

(a)If one car is chosen at random, what is the probability it has driven more than

13,000 miles last year?

(b) If a sample of 25 cars is taken, what is the probability that the mean of the

sample is less than 13,000 miles?

***A parameter is a value for a population, and a statistic

is a value for a sample.

Miles driven by millennials. In 2009, the number of miles driven per year by persons aged 16–34 was 7,900. Assume that the number of miles driven was decreasing by 300 miles per year.

a. Model this information with a linear equation.

b. Use this model to predict how many miles persons aged 16–34 will drive per year in 2019.

c. Explain why this model would not be expected to hold in 2030.

Consider a random sample of 200 one-way commute distances (in miles) from Radcliffe College to a student’s primary place of residence. The sample mean is 10.33 miles and the sample standard deviation is 3.77 miles. What percent of students sampled live between 0.81 and 19.85 miles from Radcliffe College? Suppose a student lived 25 miles from Radcliffe College. Would this commute distance be considered an outlier?

Consider a portfolio with three assets E[rA]=10% E[rB]=12% E[rC]=8%; σA2 =0.008 σB2 =0.010 σC2 =0.005; ρA,B =0.2 ρB,C = 0.0 ρA,C = −0.2

a) Consider the portfolio weights xA = 0.3 and xB = 0.3. Calculate the portfolio weight xC , the expected portfolio return, and the variance of the portfolio returns.

b) Consider the portfolio weights xA = 0.3. Calculate the expected portfolio return as a function of xB

c) Consider the portfolio weights xA = 0.3. Calculate the portfolio return variance as a function of xB

d) Calculate the portfolio which has the smallest variance, for which xA = 0.3.
