Given the following information from the performance of Apple, Amazon, S&P 500 index, and T-Bill from Oct. 216 to Oct. 2021, and the subsequent assumptions, answer the questions: 5-year average monthly return on Apple ( ER(Apple) ) 3.30% 5-year standard deviation of Apples monthly returns ( SD(Apple) ) 8.42% 5-year monthly beta of Apple 1.22 5-year average monthly return on Amazon ( ER(Amazon) ) 2.81% 5-year standard deviation of Amazons monthly returns ( SD(Amazon) ) 7.99% 5-year monthly beta of Amazon 1.16 5-year average monthly return on S&P 500 index ( ER(S&P 500) ) 1.34% 5-year standard deviation of S&P 500 indexs monthly returns ( SD(S&P 500) ) 4.42% 5-year average monthly return on T-Bill ( ER(T-Bill) ) 0.08% Assumption 1: Monthly risk-free rate (Rf) = ER(T-Bill) = 0.08% Assumption 2: Monthly expected return on the market = (RM) = ER(S&P 500) = 1.34% Assumption 3: Beta of S&P 500 index ((S&P 500)) = Market Beta = 1.00
