Please solve 46 & 47

46) 46) Sun Corporation has had retums of -6 percent, 16 percent, 18 percent, and 28 percent for the past four years. Calculate the standard deviation of the returns using the correction for the loss of a degree of freedom shown below. When variance is estimated from a sample of observed returns, we add the squared deviations and divide by N-1, where N is the number of observations. We divide by N -1 rather than to correct for a loss of a degree of freedom. The formula is Variance (rm) = v., & om-Pom). Where is the market return in period and is the mean of the values of rm A) 11.6 percent B) 13.4 percent C) 14.0 percent D) 14.3 percent 47) Stock P and Stock Q have had annual returns of -10 percent, 12 percent, and 28 percent; 47) and 8 percent, 13 percent, and 24 percent, respectively. Calculate the covariance of return between the securities. (Ignore the correction for the loss of a degree of freedom set out in the text.) A) -100.00 B) +149.00 C) -149.00 D) +99.33
