The expected return of Stellar is 17.8 percent, and the expected return of Pearl is 22.4 percent. Their standard deviations are 11.1 peftentand 19:6 percent, respectively, if a portfolio is composed of 40 percent Stellar and the rematnder Peart, catculate the expected return and the standard deviation of the portfollo, given a correlation coefficlent between Stellar and Pearl of 0.35. (Round intermediate calculations to 4 decimal places, e.3.31.2125 and final answers to 2 decimal places, e.g. 15.25\%.) Calculate the standard deviation if the correlation coefficientis -0.35 . (Do not round intermediate calculations. Round answer to 2 decimal places, es. 15.25x.)
