Problem $12-7$ Calculating Returns and Variability $[$LO$1]$

$\backslash$table$[[,$Returns$],[$Year$,x,Y,],[1,17\%,22\%,],[2,31,32,],[3,12,16,],[4,-24,-29,],[5,10,23,]]$

Using the returns shown above, calculate the arithmetic average returns, the varfiances, 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$.,\mathrm{.}16161.)$
