mestion No.1 FundInfo Corporation provides information to its subscribers to enable them to aluate the performance of mutual funds they are considering as potential investment vehicles. A cent survey of funds whose stated investment goal was growth and income produced the following ta on total annual rate of return over the past five years: Return Frequency 2 2 Annual % 11-11.9 12-12.9 13-13.9 14 14.9 5-15.9 5-16.9 "-17.9 -18.9 8 10 11 8 3 1 ) Calculate the mean, median, mode. Select the answer among parts that best reflects the central tendency of the test data. Calculate variance, and standard deviation of the annual rate of return for this sample of 45 funds. According to Chebyshev's theorem, between what values should at least 75 percent of the sample observations fall? What percentage of the observations actually do fall in that interval? Because the distribution is roughly bell-shaped, between what values would you expect to find 68 percent of the observations? What percentage of the observations actually do fall in that interval? Shortly explain the empirical rule and its importance in real life.
