Suppose that the S&P 500, with a beta of 1.0, has an expected return of 10% and T-bills provide a risk-free return of 15%. i) How would you construct a portfolio from these two assets with an expected return of 6%?

a. What would be the expected rate of return and beta of portfolios constructed from these two assets with weights in the S&P 500 of (I) 0; (II) 0.25; (III) 0.50; (IV) 0.75; (V) 1.0? (Leave no cells blank - be certain to enter "0" wherever required. Do not round intermediate calculations. Enter the value of Expected return as a percentage rounded to 2 decimal places and value of Beta rounded to 2 decimal places.)
