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

Use the following returns for X and Y.

	Returns
Year	X					Y
1			21.5	%				25.5	%
2			16.5					3.5
3			9.5					27.5
4			19.0					14.0
5			4.5					31.5

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).)
