If the simple CAPM is valid, is the above situation possible? (I am confused how to apply CAPM when we have the ER, SD, Sharpe Ratio, and Risk-Free Rate)

Question 7 Consider the following Information: \begin{tabular}{|l|r|r|} \hline Portfolio & ER & \multicolumn{1}{|c|}{ SD } \\ \hline Risk Free & 6.00 & 0.00 \\ \hline Market & 13.2 & 36 \\ \hline A & 11.2 & 25 \\ \hline \end{tabular} a. Calculate the Sharpe ratios for the market portfolio and portfolio A Sharpe Ratio=(Return on portfolio-Riskfreerate)/SD \begin{tabular}{|l|r|l|r|} \hline Market Portfo & 0.2 & Beta Market & \\ \hline Portfolio A & 0.21 & Beta A & 2.1 \\ \hline \end{tabular} b. If the simple CAPM is valid, is the above situation possible
