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. Entel 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$.16161.)$
