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

Use the following returns for X and Y.

	Returns
Year	X					Y
1			22.9	%				29.7	%
2			17.9					4.9
3			10.9					31.7
4			21.8					16.8
5			5.9					35.7

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).)

Requirement 3:

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