Can someone help me determine the correct responses to this question?

Suppose the yield on short-term government securities (perceived to be risk-free) is about 6%. Suppose also that the expected return required by the market for a portfolio with a beta of 1 is 12.0%. According to the capital asset pricing model: a. What is the expected return on the market portfolio? (Enter your answer as percentage rounded to 1 decimal places.) Expected rate of return % b. What would be the expected return on a zero-beta stock? (Enter your answer as a percentage rounded to 1 decimal places.) Expected rate of return % Suppose you consider buying a share of stock at a price of $85. The stock is expected to pay a dividend of $11 next year and to sell then for $88. The stock risk has been evaluated at B = 0.5. C-1. Using the SML, calculate the fair rate of return for a stock with a = 0.5. (Negative value should be indicated by a minus sign. Enter your answer as a percentage rounded to 2 decimal places.) Fair rate of return % C-2. Calculate your expected rate of return for the stock with a = 0.5, using the expected price and dividend for next year. (Enter your answer as a percentage rounded to 2 decimal places.) Expected rate of return %
