Problem 10-7 Calculating Returns and Variability [LO 1]

Use the following returns for X and Y.

	Returns
Year	X					Y
1			21.7	%				26.1	%
2			16.7					3.7
3			9.7					28.1
4			19.4					14.4
5			4.7					32.1

Requirement 1:

Calculate the average returns for X and Y. (Do not round intermediate calculations. Enter your answers as a percentage rounded to 2 decimal places (e.g., 32.16).)
