For some reason I can not find the proper solution for variance.

Use the following returns for X and Y Returns Year 22.4% 28.2% -44 -17 10.4 20.8 5.4 30.2 4 15.8 34.2 5 Calculate the average returns for X and Y. (Do not round intermediate calculations and enter your answers as a percent rounded to 2 decimal places, e.g., 32.16.) Average returns X 8.32 Y 14.48 % Calculate the variances for Xand Y. (Do not round intermediate calculations and round your answers to 6 decimal places, e.g., 32.161616.) Variances X Y Calculate the standard deviations for X and Y. (Do not round intermediate calculations and enter your answers as a percent rounded to 2 decimal places, e.g., 32.16.) Standard deviations 16.03 % X % Y 22.90
