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

Use the following returns for X and Y.

	Returns
Year	X					Y
1			21.1	%				24.3	%
2			16.1					3.1
3			9.1					26.3
4			18.2					13.2
5			4.1					30.3

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).)

	Average returns

Requirement 2:

Calculate the variances for X and Y. (Do not round intermediate calculations. Round your answers to 6 decimal places (e.g., 32.161616).)

	Variances

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).)
