Psychologists wish to evaluate the consistency of a standardized behavioral test. The test is designed to have a variance of 225. Twenty randomly sampled tests yield a variance of 240. Assuming the underlying population is normal, test whether the actual population variance of this test appears to be significantly greater than its designed variance. State the critical value (CV), test statistic (TS), and conclusion from the test. (Useα= 0.01.)


CV = 27.2036; TS = 20.267; fail to rejectH0



CV = 36.1909; TS = 18.377; fail to rejectH0



CV = 36.1909; TS = 20.267; fail to rejectH0



CV = 27.2036; TS = 17.8125; rejectH0
