A portfolio is composed of two stocks, A and B. Stock A has an expected return of 10% and a standard deviation of return of 24%, while stock Bhas an expected return of 8% and a standard deviation of return of 18%. If a risky portfolio of A and B has an expected return of 9.4%, what is the proportion invested in A? (Enter percentage points only. Round to integer.) the variance (not covariance) of return on the portfolio is .037, what is the correlation coefficient between the returns on A and B7 notes no risk-free awet in this problem) (Round to two decimal places)
