You are evaluating various investment opportunities currently available and you have calculated expected returns and standard deviations for five different well$-$diversified portfolios of risky assets:

Portfolio Expected Return Standard Deviation

Q $8\mathrm{.}4\%10\mathrm{.}3\%$

R $10\mathrm{.}714\mathrm{.}6$

S $4\mathrm{.}34\mathrm{.}4$

T $11\mathrm{.}316\mathrm{.}6$

U $7\mathrm{.}06\mathrm{.}8$

For each portfolio, calculate the risk premium per unit of risk that you expect to receive $([$E$($R$)-$ RFR$]/\backslash$sigma $).$ Assume that the risk$-$free rate is $4\mathrm{.}0$ percent. Round your answers to four decimal places.

Using your computations in Part $($a$),$ explain which of these five portfolios is most likely to be the market portfolio. Round your answer to four decimal places.

Portfolio

ratio of risk premium per unit of risk,

$,$ of these five portfolios so it is most likely the market portfolio.If you are only willing to make an investment with $\backslash$sigma $=8\mathrm{.}4\%,$ is it possible for you to earn a return of $8\mathrm{.}4$ percent? Do not round intermediate calculations. Round your answer to one decimal place.

possible to earn an expected return of $8\mathrm{.}4\%$ with a portfolio whose standard deviation is $8\mathrm{.}4\%.$

What is the minimum level of risk that would be necessary for an investment to earn $8\mathrm{.}4$ percent? Do not round intermediate calculations. Round your answer to one decimal place.

$\%$

What is the composition of the portfolio along the CML that will generate that expected return? Round your answers to four decimal places.
