2.  (10pts) What is the expected return and standard deviation of a portfolio that has weight ω = 0.5 on the risk-free rate and 1 ? ω = 0.5 in the S&P 500index?

3.  (10pts) What are the weights on a portfolio, ω for investing in the risk-free rateand 1 ? ω for investing in the S&P 500 index, that produce a standard deviation that is  0.04? What is the expected return on that portfolio?
