5. (20 points) Consider the following list of projects (data in millions): PW (15%) $716 $757 $179 oPW $544 $616 $40 Alternative Payback Investment $471 $465 $405 2 4 2 Assume that all three projects are mutually exclusive. a. Are any projects dominated? Explain. b. Use threshold analysis with a minimum present-worth standard of maximum standard deviation of $600 million, and a maximum payback of 4 (assume that the payback period for a portfolio is the maximum payback period of any project in the portfolio). What projects should be considered? Assume that the criteria of present worth, standard deviation, and payback period are ordered as listed, with ideal values of $1 billion, $20 million, and 2 respectively. Provide a score for each portfolio and select the best one. c. d. Using only the PW and standard deviation, apply the Freund utility model with B = 0.05 described in Problem 3 to the portfolios to identify the best one
