Answer:
8.01%
Step-by-step explanation:
Expected return on mutual fund = Risk-free rate + Market risk premium*Beta
Expected return on mutual fund = 3% + 7.7%*1
Expected return on mutual fund = 10.70%
Best estimate of the portfolio expected rate of return = Weight of mutual fund*Expected return on mutual fund + Weight of risk-free Treasury bills*Expected return on risk-free Treasury bills
Best estimate of the portfolio expected rate of return = 65%*10.70 + 35%*3
Best estimate of the portfolio expected rate of return = 0.08005
Best estimate of the portfolio expected rate of return = 8.01%
