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 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., 32.16. Enter your variance answers rounded to 5 decimal places, e.g., .16161.)
