Chapter 7.2, Problem 9E
Returns on Mutual Finds. The Wall Street Journal provides the net asset value, the year-to-date percent return, and the three-year percent return for 882 mutual funds at the end of 2017. Assume that a simple random sample of 12 of the 882 mutual funds will be selected for a follow-up study on the size and performance of mutual funds. Use the fourth column of the random numbers in Table 7. 1, beginning with 51102, to select the simple random sample of 12 mutual funds. Begin with mutual fund 102 and use the last three digits in each row of the fourth column for your selection process. What are the numbers of the 12 mutual funds in the simple random sample?
