together a portfolio made up of four different stocks. However, you are considering two possible weightings: a$.$ The beta on the first portfolio is $($Round to three decimal places.$)$ The beta on the second portfolio is $($Round to three decimal places.$)$ b$.$ Which portfolio is riskier? $($Select $-$ the best choice below.$)$ A$.$ The first portfolio because the beta is smaller. B$.$ The second portfolio because the beta is smaller. C$.$ The first portfolio because the beta is larger. D$.$ The second portfolio because the beta is larger. c$.$ If the risk$-$free rate of interest were $4\mathrm{.}5\%$ and the market risk premium were $6\%,$ then the rate of return on the first portfolio is expected to be $\_\%($Round to two decimal places.$)$ Data table $\backslash$table$[[,$ Portfolio Weightings,$],[$Asset$,$ Beta, First Portfolio, Second Portfolio$],[$A$,2\mathrm{.}10,20\%,30\%$
