Everything I have is correct, but I cannot figure out how to get Y for both standard deviations and the variances. can someone show me how to get Y for both. Please and Thanks in advance

Use the following returns for X and Y Returns ear 21.7% 26.1% -16.7 9.7 19.4 28.1 -14.4 32.1 4 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).) returns 7 76190 13.64 % 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 023531 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).) Standard deviations 15.34%
