Returns Year Y 1 16 % 22 % 2 30 31 3 11 12 4 - 23 - 28 5 10 22 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. Y 8.80 % 11.80 % Average returns Variances 17.42400 x 424.61183 x Standard deviations 303.59 X % 20.61 X %
