a. (7 points) Suppose an investor is appraising an investment under the following conditions: Forecast NPV P 1 30,000 0.15 2 20,000 0.15 3 15,000 0.50 4 10,000 0.20 (i) (ii) (iii) Find the investment's expected value, standard deviation, and the coefficient of variation. Would the risk-averse investor prefer this investment to a risk-free investment with a NPV of $10,000? Explain. Would the risk-averse investor prefer this investment with an expected NPV of $12,000 and a standard deviation of $12,000? Explain b. (3 point) In evaluating two risky investments, would choosing the investment with the higher coefficient of variation imply a higher or lower degree of risk aversion? Explain your answer.
