ons Exercise 11.16 Algo (Inferences About Two Population Variances) Question 2 of 5 Check My Work (3 remaining) Investors commonly use the standard deviation of the monthly percentage return for a mutual fund as a measure of the risk for the fund; in such cases, a fund that has a larger standard deviation is considered more risky than a fund with a lower standard deviation. The standard deviation for the American Century Equity Growth fund and the standard deviation for the Fidelity Growth Discovery fund were reported to be 14.9% and 18.8%, respectively. Assume that each of these standard deviations is based on a sample of 60 months of returns. Do the sample results support the conclusion that the Fidelity fund has a larger population variance than the American Century fund? Which fund is more risky? State the null and alternative versions of the research hypothesis that the Fidelity fund has a larger population variance than the American Century fund. Let the Fidelity fund be represented by population 1.
