Question
In the Izmir University of Economics, a professor claims that exam scores for non-accounting majors are more variable than for accounting majors. Random samples of 26 non-accounting majors and 26 accounting majors are taken from
2019. Test at the 5% 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.
final exam held on
Non-Accounting
nx = 26
s = 1502.588
Accounting
ny = 26
= 468.274
To test the professor's claim, identify the null and alternative hypotheses. The null hypothesis is represented by H, and the alternative hypothesis is represented by H,. Choose the correct answer below.
O A. Ho: o =
OB.
O C. Ho: =
OD.
The test statistic is F=
(Round to three decimal places as needed.)
The critical value is
(Round to two decimal places as needed.)
Since the test statistic is
V the critical value,
V the null hypothesis. There is
V evidence to support the professor's claim at the 5% level.
