(See picture)
A. Reject HO if the test statistic is greater than 1.645 or less than -1.645.
B . Reject HO if the test statistic is greater than 2.575 or less than -2.575.
C. Reject HO if the test statistic is greater than 1.96 or less than -1.96
D. Reject HO if the test statistic is greater than 2.33 or less than -2.33
E. None of the other choices is correct
Suppose you want to test the claim that µ≠ 31.5, with known o. If the sample size is n = 81 and the level of significance a = 0.1, when should you reject Ho?
Let 20.005 = 2.575, 20.012.33, 20.025 = 1.96 and 20.05 = 1.645.
