For problems 9 and 10, assume that the true population mean of 3-year percent returns is 15 and the true population standard deviation of 3-year percent returns is 3. 9. Assume the distributions are approximately normally distributed. What percent of the 3- year percent return values are greater than 18? Table of Normal Probabilities 10. What is the probability that a sample of 20 funds will have a mean value of less than 12 or greater than 18? Table of Normal Probabilities Do you need to rely on the Central Limit Theorem in order to solve this problem? Explain briefly
