A financial analyst examines the performance of two mutual funds and claims that the variances of the annual returns for the bond funds differ. To support his claim, he collects data on the annual returns (in percent) for the years 2001 through 2010. The analyst assumes that the annual returns for the two emerging market bond funds are normally distributed. Use the following summary statistics. The competing hypotheses are Η₀: / = 1, Η_A: / ≠ 1. At α = 0.10, is the analyst's claim supported by the data using the critical value approach? A) No, because the value of the test statistic is less than the critical F value. B) Yes, because the value of the test statistic is less than the critical F value. C) Yes, because the value of the test statistic is greater than the critical F value. D) No, because the value of the test statistic is greater than the critical F value.
