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

Consider the following information:

$\backslash$table$[[$State of Economy,$\backslash$table$[[$Probability of State$],[$of Economy$]],\backslash$table$[[$Rate of Return if State$],[$Occurs$]]],[$Stock A$,$Stock B$],[$Recession$,0\mathrm{.}15,0\mathrm{.}06,-0\mathrm{.}19],[$Normal$,0\mathrm{.}55,0\mathrm{.}11,0\mathrm{.}14],[$Boom$,0\mathrm{.}30,0\mathrm{.}19,0\mathrm{.}29]]$

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

$\backslash$table$[[$Stock A$,$Expected return$],[$Stock B$,]]$

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