Suppose that the index model for stocks A and B is estimated from excess returns with the following results:

RA $=4\mathrm{.}5\%+1\mathrm{.}40$RM $+$ eA

RB $=2\mathrm{.}2\%+1\mathrm{.}7$RM $+$ eB

$\backslash$sigma M $=24\%$; R$-$squareA $=0\mathrm{.}30$; R$-$squareB $=0\mathrm{.}20$

What is the standard deviation of each stock? $($Do not round intermediate calculations. Round your answers to $2$ decimal places.$)$
