Problem 10-7 Calculating Returns and Variability

	Returns
Year	X	Y
1		11	%		18	%
2		25			26
3		18			23
4		11			10
5		10			17

Using the returns shown above, calculate the average returns, the variances, and the standard deviations for X and Y (Do not round intermediate calculations and round your final percentageanswer to 2 decimal places. (e.g., 32.16)and variances to 5 decimal places. (e.g., 32.16161))

	X	Y
