Using the returns shown above, calculate the arithmetic average returns, the variances, and the standard deviations for X and Y. (Do not round intermediate calculations. Enter your average return and standard deviation as a percent rounded to 2 decimal places, e.g., 32.16, and round the variance to 5 decimal places, e.g., .16161.)
I really only need the variances. I've attached a picture showing the correct answers for average returns and standard deviation, as well as the INCORRECT answers I got for the variance.
Please do not give me the same incorrect answers.
