$\backslash$table$[[$Returns$],[$Year$,x,Y,],[1,16\%,22\%,],[2,30,31,],[3,11,,],[4,-23,-28,],[5,10,22,]]$

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 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$.,16161.)$
