Transcribed Image Text:A professor claims that exam scores for non-accounting majors are more variable than for accounting
majors. Random samples of 29 non-accounting majors and 29 accounting majors are taken from a final
exam. Test at the 1% level the null hypothesis that the two population variances are equal against the
alternative that the true variance is higher for the non-accounting majors. Assume the populations are
normally distributed.
