Problem $13-7$ Calculating Returns and Standard Deviations $($LO$1)$

Consider the following information:

$\backslash$table$[[,$Probability of State of$,$Rate of Return if State Occurs$],[$State of Economy,Economy,Stock A$,$Stock B$],[$Recession$,0\mathrm{.}15,0\mathrm{.}08,-0\mathrm{.}15],[$Normal$,0\mathrm{.}55,0\mathrm{.}17,0\mathrm{.}16],[$Boom$,0\mathrm{.}30,0\mathrm{.}20,0\mathrm{.}20]]$

Calculate the expected return for each stock. $($Do not round intermediate calculations. Round the final answers to $2$ decimal places.$)$

Calculate the standard deviation for each stock. $($Do not round intermediate calculations. Round the final answers to $2$ decimal places.$)$
