Using CAPM determine the required rate of return on the following:

            a.         Rf = 3.10%                   b.         Rf = 5.95%                   c.         Rf = 2.29%

                        Rm = 10.12%                           Rm = 12.37%                           Rm = 8.58%

                        b= 1.21                                   b= 0.78                                   b= 1.55
