$r($ Fincorp $)=\mathrm{.}001+\mathrm{.}8r(S$&$P500)+e$

The standard deviation of the monthly return on the S&P $500$ was $\mathrm{.}05.$

The standard deviation of the monthly value of the residual, $e,$ was $\mathrm{.}03.$

c$.$ What was the standard deviation of the return on FinCorp stock? Remember that e

and the return on the S&P $500$ are essentially uncorrelated.
