4 An investor wants to invest $300,000 in a portfolio of three mutual funds. The annual fund returns are normally distributed with a mean of 4% and standard deviation of 0.5% for the short-term investment fund, a mean of 7% and standard deviation of 4% for the intermediate-term fund, and a mean of 8.3% and standard deviation of 3% for the long-term fund. An initial plan for the investment allocation is 45% in the short-term fund, 35% in the intermediate-term fund, and 20% in the long-term fund. a. Use Analysis ToolPak, with a seed of 1, to develop a Monte Carlo simulation with 1000 trials to estimate the mean ending balance after the first year. Note: Round the final answer to two decimal places. Answer is complete but not entirely correct. Mean ending balance after the first year $ 17,730.00 x b. If the allocation is changed to 30% short-term, 55% intermediate-term, and 15% long-term, estimate the ending balance after the first year. Note: Round the final answer to two decimal places. > Answer is complete but not entirely correct. Mean ending balance after the first year $ 18,985.00 c. Compare the two investment strategies in parts a and b and choose the most appropriate answer from the following choices. On average, the investment strategy in part a is more risky and yields a lower return.
