Consider the following table: Required: a$.$ Calculate the values of mean return and variance for the stock fund. $($Do not round intermediate calculations. Round "Mean return" value to $1$ decimal place and "Variance" to $2$ decimal places.$)$ b$.$ Calculate the value of the covariance between the stock and bond funds. $($Negative value should be indicated by a minus sign. Do not round intermediate calculations. Round your answer to $2$ decimal places.$)$ Covariance Consider the following table:
