A test of a two-tail hypothesis rejects the null hypothesis at the 5% level of significance. What will the decision be for an appropriate one tail test at the 2.5% level of significance?
Select one:
a. It is not possible to decide, as we do not know if p-value < 0.025.
b. Since p-value < 0.025 there is sufficient evidence to reject the null hypothesis.
c. Since p-value > 0.025 we fail to reject the null hypothesis.
d. The one-tail test will have the same p-value as the two tail test, so we will again reject the one tail null hypothesis.
