A test of a two-tail hypothesis rejects the null hypothesis

Reference no: EM13644451

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.
