(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.) Answer is complete but not entirely correct. % % Average return Variance Standard deviation X 10.40 1.54300 > 12.42 Y 11.80 6.80700 26.09 % %
