Given:

E$($R $1)=0\mathrm{.}12$

E$($R $2)=0\mathrm{.}16$

E$(\backslash$sigma $1)=0\mathrm{.}05$

E$(\backslash$sigma $2)=0\mathrm{.}06$

Calculate the expected returns and expected standard deviations of a two$-$stock portfolio having a correlation coefficient of $0\mathrm{.}60$ under the conditions given below. Do not round intermediate calculations. Round your answers to four decimal places.
