Problem $13-19$ Reward$-$to$-$Risk Ratios $[$LO$4]$

Stock $Y$ has a beta of $1\mathrm{.}5$ and an expected return of $17\mathrm{.}6$ percent. Stock $Z$ has a beta of

$1\mathrm{.}0$ and an expected return of $12\mathrm{.}3$ percent. What would the risk$-$free rate have to be for

the two stocks to be correctly priced? $($Do not round Intermedlate calculations and

enter your answer as a percent rounded to $2$ decimal places, e$.$g$.,32\mathrm{.}16.)$
