Jim and Mike have been comparing their investment portfolios for several years. Jim claims that his portfolio of only stocks has a better record than Mike's portfolio that is 20% stocks and 80% bonds. Let x be a random variable representing the annual percent return for Jim's portfolio and let y be a random variable representing the annual return on Mike's portfolio. Use this information to calculate the coefficient of variation for Jim's portfolio. Round your answer to two decimal places. –5 15 15 –2 18 13 28 –5 9 20 30 –2 25 –7 2 –8 –9 22 27 22 ​ 94.25% 106.10% 159.55% 62.68%
