Textbook Problem

Explain how the power of a hypothesis test is influenced by each of the following. Assume that all other factors are held constant.

**a.** Increasing the alpha level from .01 to .05

**b.** Changing from a one-tailed test to a two-tailed test

a.

To determine

The effect of increasing the alpha level on a power of a hypothesis test.

Explanation

**Given:**

The alpha level increases from 0.01 to 0.05.

**Justification:**

Larger the alpha level increases power of the test it is because alpha level shows the situation of rejecting the null hypothesis when it is true and increases the alpha level also means increase in critical region...

b.

To determine

The effect of changing from one tailed test to a two tailed test on a power of a hypothesis test.
