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

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

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