A stock has a required return of $13\%,$ the risk$-$free rate is $5\mathrm{.}5\%,$ and the market risk premium is $5\%.$

a$.$ What is the stock's beta? Round your answer to two decimal places.

I. If the stock's beta is equal to $1\mathrm{.}0,$ then the change in required rate of return will be greater than the change in the market risk premium.

II$.$ If the stock's beta is equal to $1\mathrm{.}0,$ then the change in required rate of return will be less than the change in the market risk premium.

III. If the stock's beta is greater than $1\mathrm{.}0,$ then the change in required rate of return will be greater than the change in the market risk premium.

IV$.$ If the stock's beta is less than $1\mathrm{.}0,$ then the change in required rate of return will be greater than the change in the market risk premium.

V$.$ If the stock's beta is greater than $1\mathrm{.}0,$ then the change in required rate of return will be less than the change in the market risk premium.

Stock's required rate of return will be
