What is the expected return and the variance for a portfollo that invests 63% in the stock fund and 37% in the money market fund? (Hint Note that the correlation coofficient between the portfolio and the money market find is zera) (Round intermediate calculations. to at least 4 decimal places and final answers to 2 decimal places.)
