1. In a study published in Medicine and Science in Sports and Exercise (volume 17, no.2, page 189) the measurements of 252 men (ages 22 – 81) are given. Of the 14 measurements taken of each man, some have significant correlations and others don’t. The partial table shown below lists only the first 9 rows of data and 9 of the measurements.

1. Using your intuition, classify the following (x, y) pairs as having a weak correlation (0 < r < 0.5), a moderate correlation (0.5 < r < 0.8), or a strong correlation (0.8 < r < 1.0).

1. (weight, neck)                       i         (weight, height)

iii. (age, wrist)                            iv.        (weight, body fat)

v.   (chest, hip)                             vi.        (age, weight)

vii. (chest, neck)                          viii.      (height, knee)

2. Pick 3 pairs from (a) and calculate the correlation coefficient.   Compare the results with those obtain by intuition in part a. You only need to calculate the actual correlation coefficient for these 3. In part a, you are ‘guessing’ if the correlation coefficient is weak, moderate or strong.

3. Find the regression line (‘best fit line’) for the pairs (weight, neck) and (weight, body fat). You will have 2 equations for lines.

4. Use the results of part c to predict the following.

1. The neck circumference of a man whose weight is 180 pounds.
2. The body fat of a man whose weight is 180 pounds.

Use the CO2 data and via Multiple regression select the two variables that predict the CO2 level with the best P-value. Make another table with these two variables and answer the questions. Numerical answers are rounded so choose the answer that matches the best:

Suppose the inflation rate is expected to be 6% next year, 4.9% the following year, and 2.9% thereafter. Assume that the real risk-free rate, r*, will remain at 1.7% and that maturity risk premiums on Treasury securities rise from zero on very short-term bonds (those that mature in a few days) to 0.2% for 1-year securities. Furthermore, maturity risk premiums increase 0.2% for each year to maturity, up to a limit of 1.0% on 5-year or longer-term T-bonds.

For this, problem, please include the excel procedure you used to arrive at an answer (screenshots, explanation, actual file, etc.).

The American Association of Individual Investors (AAII) On-Line Discount Broker Survey polls members on their experiences with electronic trades handled by discount brokers. As part of the survey, members were asked to rate their satisfaction with the trade price and the speed of execution, as well as provide an overall satisfaction rating. Possible responses (scores) were no opinion (0), unsatisfied (1), somewhat satisfied (2), satisfied (3), and very satisfied (4). For each broker, summary scores were computed by computing a weighted average of the scores provided by each respondent. A portion the survey results follow (AAII web site, February 7, 2012).

A. Develop an estimated regression equation using trade price and speed of execution to predict overall satisfaction with the broker. Interpret the coefficient of determination.

B. Use the t test to determine the significance of each independent variable. What are your conclusions at the 0.05 level of significance?

C. Interpret the estimated regression parameters. Are the relationships indicated by these estimates what you would expect?

D. Finger Lakes Investments has developed a new electronic trading system and would like to predict overall customer satisfaction assuming they can provide satisfactory service levels (3) for both trade price and speed of execution. Use the estimated regression equation developed in part (a) to predict overall satisfaction level for Finger Lakes Investments if they can achieve these performance levels.

E. What concerns (if any) do you have with regard to the possible responses the respondents could select on the survey

Consider the following information on Huntington Power Co. Debt:

4,000, 7% semiannual coupon bonds outstanding, $1,000 par value, 18 years to maturity, selling for 102 percent of par; the bonds make semiannual payments. Preferred Stock: 10,000 outstanding with par value of $100 and a market value of 105 and $10 annual dividend. Common Stock: 84,000 shares outstanding, selling for $56 per share, the beta is 2.08

The market risk premium is 5.5%, the risk free rate is 3.5% and Huntington’s tax rate is 32%.

Huntington Power Co. is evaluating two mutually exclusive project that is somewhat riskier than the usual project the firm undertakes; management uses the subjective approach and decided to apply an adjustment factor of +2.1% to the cost of capital for both projects.

Project A is a five-year project that requires an initial fixed asset investment of $2.4 million. The fixed asset falls into the five-year MACRS class. The project is estimated to generate $2,050,000 in annual sales, with costs of $950,000. The project requires an initial investment in net working capital of $285,000 and the fixed asset will have a market value of $225,000 at the end of five years when the project is terminated.

Project B requires an initial fixed asset investment of $1.0 million. The marketing department predicts that sales related to the project will be $920,000 per year for the next five years, after which the market will cease to exist. The machine will be depreciated down to zero over four-year using the straight-line method (depreciable life 4 years while economic life 5 years). Cost of goods sold and operating expenses related to the project are predicted to be 25 percent of sales. The project will also require an addition to net working capital of $150,000 immediately. The asset is expected to have a market value of $120,000 at the end of five years when the project is terminated.

Use the following rates for 5-year MACRS: 20%, 32%, 19.2%, 11.52%, 11.52%, and 5.76%

1) Calculate project A’s cash flows for years 0-5

2) Calculate NPV, IRR and PI for project A

3) Calculate project B’s cash flows for year 0-5

4) Calculate NPV, IRR and PI for project B

5) Which project should be accepted if any and why?

6) What is the exact NPV profile’s crossover rate (incremental IRR)?
