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. Non-Accounting Accounting A. Ho: H₁: 2 2 0² = 0² C. Ho: o² = 0² H₁:0² #0² nx the alternative hypothesis is represented by H₁. Choose the correct answer below. OB. Ho: 0²20² H₁:0² <0² The test statistic is F = = 29 = 29 2 Sx = 1611.016 2 S = 446.238 Ho: 0² = 0² H₁:0² <0² (Round to three decimal places as needed.)

Question
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. Non-Accounting Accounting 2 A. H₂:0²=0² H₁:0² > 0² Ho: H₁:0² +0² The test statistic is F = = 29 nx= ny = 29 2 S S 2 the alternative hypothesis is represented by H₁. Choose the correct answer below. B. Ho: 0²20² H₁:0² <0 = 1611.016 = 446.238 ○D. H₂:0² = 0² H₁:0² <0² (Round to three decimal places as needed.)
