4. An investor has the utility function listed in problem 3 and is considering investing in a risky asset with an expected return of 14.75% and a standard deviation of 32% and a Treasury bill with a rate of return of 2.25%. If the investors coefficient of risk aversion constant A is 2.0, what is their optimal portfolio weight to invest in the risky asset? Enter your answer rounded to two decimal places. Do not enter % in the answer box. For example, if your answer is 0.12345 or 12.345% then enter as 12.35 in the answer box.

5. Using the information from problem 4, the investor decides that the optimal weight to invest in the risky asset y* calculated in problem 4 seems too low, and so the investor decides to invest a higher percent of the complete portfolio, namely 90%, in the risky asset to raise both the risk and the expected return for the complete portfolio. What is the expected return for the non-optimal complete portfolio with this increased level of risk? Enter your answer rounded to two decimal places. Do not enter % in the answer box. For example, if your answer is 0.12345 or 12.345% then enter as 12.35 in the answer box.
