The Heaton Electronics Company produces SD memory cards in sizes ranging from 2GB to 32GB. The management team are looking at options for growing the company in the future. The company has identified three options for growth.

• Keep the product range the same but increase the factory capacity to produce more of the products
• Expand the product range to include larger memory cards (up to 124 GB)
• Invest in new technology for manufacturing cards with extremely large memory sizes.

The management team believe that the profit (after investment) over the next three years will depend on whether the demand for the larger memory card sizes grows slowly, moderately or at a rapid rate. The potential profit under each market condition is shown below

Part e)

The company narrow down the choice to either expanding the product range or investing in new technology. Both projects generate cash flow at different stages of the project. The cash flow generated at each stage is shown below. Using a discount rate (r) of 2.5%, calculate the Net Present Value (NPV) for both projects and determine the best decision based on the NPV.

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.

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
