How to solve

Using the returns shown above, calculate the arithmetic average returns, the variances, and the standard deviations for $x$ and $Y.$

Note: Do not round intermediate calculations. Enter your average return and standard deviation answers as a percent rounded to

$2$ decimal places, e$.$g$.,32\mathrm{.}16,$ and round the variance answers to $5$ decimal places, e$.$g$.,16161.$
