Problem 12-7 Calculating Returns and Variability [LO1]

	Returns
Year	X			Y
1		11	%		23	%
2		15			26
3		10			11
4		13			14
5		10			16

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 as a percent rounded to 2 decimal places, e.g., 32.16, and round the variance to 5 decimal places, e.g., 32.16161.)
