Suppose your expectatlons regarding the stock price are as follows:

Use the equations $E(r)={}_{s}p(s)r(s)$ and ${}^2={}_{s}p(s)[r(s)-E(r){]}^2$ to compute the mean and standard

devlation of the HPR on stocks.

Note: Do not round Intermedlate calculatlons. Round your answers to $2$ declmal places.
