You manage a risky portfolio with an expected rate of return of 19% and a standard deviation of 33%. The T-bill rate is 7%. Your risky portfolio includes the following investments in the given proportions:

Stock A	29	%
Stock B	36	%
Stock C	35	%

Suppose that your client decides to invest in your portfolio a proportion y of the total investment budget so that the overall portfolio will have an expected rate of return of 16%. a. What is the proportion y? (Round your answer to the nearest whole number.) b. What are your clients investment proportions in your three stocks and the T-bill fund? (Do not round intermediate calculations. Round your answers to 2 decimal places.) c. What is the standard deviation of the rate of return on your clients portfolio? (Do not round intermediate calculations. Round your answer to 2 decimal places.)

2-Consider a portfolio that offers an expected rate of return of 11% and a standard deviation of 26%. T-bills offer a risk-free 7% rate of return. What is the maximum level of risk aversion for which the risky portfolio is still preferred to T-bills? (Do not round intermediate calculations. Round your answer to 2 decimal places.)
