1. Calculate the beta of the stock when it has an expected return of 17.8 percent, the return on the market is 13.1 percent and the risk-free rate of return is 3.3 percent. (Round your answer to 2 decimal places. E.g., 1.23)

2. Suppose XYZ Inc.s target capital structure is as follows: weight of debt = 45%, weight of preferred shares = 5%, and weight of common equity = 50%. Its before-tax cost of debt is 8%, its cost of equity is 10.8%, its cost of preferred stock is 8.4%, and its tax rate is 40%. Calculate XYZs WACC. (Do not round intermediate calculations and round your answer to 2 decimal places. Input percentage points only, no % sign, e.g., 32.16)

3. The risk-free rate of return is 5.8 percent and the market risk premium is 13 percent. What is the expected rate of return on a stock with a beta of 1.56? (Do not round intermediate calculations and round your answer to 2 decimal places, e.g., 32.16. Input percentage points only, no % sign)
