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 0.02% and standard deviation of 0.30% for the short-term investment fund, a mean of 0.05% and standard deviation of 0.03% for the intermediate-term fund, and a mean of 0.062% and standard deviation of 0.03% 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 100 trials to estimate the mean ending balance after the first year. Note: Round the final answer to two decimal places. Mean ending balance after the first year 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. Mean ending balance after the first year
