Which of the following statements is (are) true regarding 1-tailed and 2-tailed

Question

Which of the following statements is (are) true regarding 1-tailed and 2-tailed hypothesis tests? Check all that apply.
Note: Consider this carefully. There may be more than one correct answer and there is no partial credit for getting only one selection correct. Also note that, when considering a 1-tailed test, assume that we are excluding the possibility of getting a test statistic in the 'wrong' tail, i.e. the tail which does not contain the critical value.

For this problem, you have five tries.

A.Failing to reject a 2-tailed test means that you will reject the corresponding single tailed test at the same level

B.Failing to reject a 1-tailed test implies that you would fail to reject the corresponding 2-tailed test at the same alpha level

C.Failing to reject a 2-tailed test implies that you would also fail to reject the corresponding 1-tailed test at the same significance level

D.Rejecting a 1 tailed test implies that you would fail to reject the corresponding 2 tailed test at the same level

E.Rejecting a 2-tailed test implies that you would also reject the corresponding 1-tailed test at the same significance level

F.Rejecting a 1-tailed test implies that you would also reject the corresponding 2-tailed test at the same significance level

Explanation / Answer

B.Failing to reject a 1-tailed test implies that you would fail to reject the corresponding 2-tailed test at the same alpha level

E.Rejecting a 2-tailed test implies that you would also reject the corresponding 1-tailed test at the same significance level
