Problem 10-7 Calculating Returns and Variability

	Returns
Year	X	Y
1		14	%		18	%
2		28			29
3		21			26
4		9			10
5		10			20

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
Average returns	8%	10.2%
Variances	??????	???????????
Standard deviations	17.90%	21.34%
