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

Using the following returns for X and Y.

	Returns
Year	X					Y
1			21.2	%				24.6	%
2			16.2					3.2
3			9.2					26.6
4			18.4					13.4
5			4.2					30.6

Requirement 1:

Calculate the average returns for X and Y.(Do not include the percent signs (%). Round your answers to 2 decimalplaces (e.g., 32.16).)

	Average returns
X	%
Y	%

Requirement 2:

Calculate the variances for X and Y.(Round your answers to 6 decimal places(e.g., 32.161616).)

	Variances
X
Y

Requirement 3:

Calculate the standard deviations for X and Y.(Do not include the percent signs (%). Round your answers to 2 decimal places (e.g., 32.16).)

	Standard deviations
