Consider the following table:

scenario Probability Stock Fund Rate of Return Bond Fund Rate of return

Severe recession 0.05 -27% -12%

MIld recession 0.25 -7% 18%

severe recession 0.40 12% 11%

boom 0.30 17% -8%

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.)

Mean return %

Variance %-Squared

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 %-Squared
