Use the required return-beta equation from the CAPM.

1. What is the required return if the risk-free rate is 3%, beta 1.5 and the required return for the market portfolio is 8%?

2. What is the risk-free rate if beta is 1.1, the required return 8.4% and the required return for the market portfolio is 8%?

3. What is beta if the risk-free rate is 3%, the required return 10% and the required return for the market is 8%?

4. What is the required return for the market if the risk-free rate is 3%, beta 1.5 and the required return 10%?
