Can someone help me solve this question and show all work

3. Suppose that the market expected return is 10% with standard devia- tion of 20%. Assume further the risk-free rate is 5%. You are consider- ing an active investment strategy (call it A). Your analysis indicates that A has an expected return of 8% with standard deviation 30%. 2 In addition suppose you find that the correlation between the market return and the return to strategy A is 0.3. (a) What is the beta of strategy A? (b) How much of the volatility of A is due to systematic risk as mea- sured by market exposure? (c) What is the alpha of strategy A? Is the market mean-variance efficient? Why or why not? (d) How would you combine strategy A with the market portfolio to improve on the performance of the market portfolio? (e) Show how to use strategy A, the market portfolio and the risk-free return to create a portfolio with higher expected return than the market but that matches the risk of the market portfolio
