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.,
32.16161.)
