P12-7 Calculating Returns and Variability [LO1]

Using the following returns calculate the arithmetic average returns the variances and the standard deviations for X and Y.
(Pay particular attention to the format of your answer. The answers for the returns and standard deviations need to be given in %
format however the answers for the variances need to be given in DECIMAL format. Remember that the variance is a squared return
therefore it cannot be stated in % format. Do not include the percent signs (%). For average return and standard deviation round your
answers to 2 decimal places (e.g. 32.16) and for variance round your answers to 6 decimal places. (e.g. 32.161616))
