There are three funds: Expected Return Standard Deviation 10% 15% 15% 25% T-Bill 5% Also, one of the efficient portfolios (but not an optimal risky_portfolio), Y, which consists of two risky assets (A and B), and T-bill funds has expected return of 11.3% and standard deviation of 11.6%. (Hint: this efficient portfolio, Y, is on the best feasible capital allocation line). What is the expected return of the efficient portfolio, X, which has the same standard deviation as A (i.e., 15%)?
