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