question: 1 point(s) possible Submit quiz A teacher claims that her students' test scores are getting more consistent and now have a lower variation than 2.31, the variation in previous terms. She conducts a hypothesis test. She calculates her test statistic to be x2 = 17.875 She looks up the critical value for this test and finds it to be = 20.834. What can she conclude? Hint: Set-up Ho and H₁ first, draw a sketch and read the answer choices carefully! OA. The test statistic falls in the critical (rejection) region for this test. Therefore, there is sufficient evidence to support her claim. OB. The test statistic does not fall in the critical (rejection) region for this test. Therefore, there is sufficient evidence to support her claim. OC. The test statistic falls in the critical (rejection) region for this test. Therefore, there is not sufficient evidence to support her claim. OD. The test statistic does not fall in the critical (rejection) region for this test. Therefore, there is not sufficient evidence to support her claim.
