Problem 12-7 Calculating Returns and Variability [LO1]

	Returns
Year	X			Y
1		12	%		23	%
2		15			27
3		11			11
4		12			13
5		10			17

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.)
