Project A B C D Expected return 12.8% 11.7% 12.9% 13.1% Range 5.5% 3.9% 5.9% 4.1% Standard deviation 3.2% 3.8% 2.8% 3.1% a. Which project is least risky, judging on the basis of range? (Select the best answer below.) A. Project A B. Project D c. Project B OD. Project C b. Which project is least risky, judging on the basis of standard deviation? (Select the best answer below.) O A. Project B OB. Project D O c. Project C OD. Project A Explain why standard deviation may not be an entirely appropriate measure of risk for purposes of this comparison. (Select the best answer below.) O A. The standard deviation measure fails to take into account both the volatility and the return of the investment. Investors would prefer higher return but less volatility, and the coefficient of variation provides a measure that takes into account both aspects of investors' preferences. OB. The standard deviation measure fails to take into account both the volatility and the return of the investment. Investors would prefer lower return but higher volatility, and the coefficient of variation provides a measure that takes into account both aspects of investors' preferences. O C. The standard deviation measure fails to take into account both the risk-free rate and the return of the investment. Investors would prefer higher return but less volatility, and the coefficient of variation provides a measure that takes into account both aspects of investors' preferences. OD. The standard deviation measure fails to take into account both the volatility and the risk-free rate. Investors would prefer higher return but less volatility, and the coefficient of variation provides a measure that takes into account both aspects of investors' preferences. c. The coefficient of variation for project A is (Round to three decimal places.) The coefficient of variation for project B is (Round to three decimal places.) The coefficient of variation for project C is (Round to three decimal places.) The coefficient of variation for project Dis. (Round to three decimal places.) c. The coefficient of variation for project A is (Round to three decimal places.) The coefficient of variation for project Bis (Round to three decimal places.) The coefficient of variation for project is 1. (Round to three decimal places.) The coefficient of variation for project Dis (Round to three decimal places.) Which project will Greengage's owners choose, judging on the basis of coefficient of variation? (Select the best answer below.) O A. Project B. Project A C. Project B OD.
