Year Returns - X Y 11 % 23% 15 26 10 11 - 13 - 14 10 16 3 4 5 Using the returns shown above, calculate the arithmetic average returns, the variances, and the standard deviations for X and Y. (Do not round intermediate calculations. Enter your average return and standard deviation as a percent rounded to 2 decimal places, e.g., 32.16, and round the variance to 5 decimal places, e.g., .16161.) Answer is complete but not entirely correct. % % Average returns Variances Standard deviations 6.60 252.29986 11.15 Y 12.40 252.17440 15.88 % %
