The expected return of Culver is 17.7 percent, and the expected return of Larkspur is 22.7 percent. Their standard deviations are 11.7 percent and 19.7 percent, respectively. If a portfolio is composed of 35 percent Culver and the remainder Larkspur, calculate the expected return and the standard deviation of the portfolio, given a correlation coefficient between Culver and Larkspur of 0.35. (Round intermediate calculations to 4 decimal places, e.g. 31.2125 and final answers to 2 decimal places, e.g. 15.25%.)
