Consider the following information:

$\backslash$table$[[,,$Rate of Return if State Occurs$],[$State of Economy,Probability of State of$,$Stock A$,$Stock B$],[$Recession$,$Economy,$0\mathrm{.}10,-0\mathrm{.}17],[$Normal$,0\mathrm{.}15,0\mathrm{.}19,0\mathrm{.}18],[$Boom$,0\mathrm{.}55,0\mathrm{.}22,0\mathrm{.}22]]$

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

Calculate the standard deviation for each stock. $($Do not round intermediate calculations. Round the final answers to $20$ places.$)$
