Textbook Problem

For a 5-point treatment effect, a researcher computes power of *p* = 0.50 for a two-tailed hypothesis test with α = .05.

**a.**Will the power increase or decrease for a 10-point treatment effect?**b.**Will the power increase or decrease if alpha is changed to α = .01?**c.**Will the power increase or decrease if the researcher changes to a one-tailed test?

**a.**

To determine

If the power will increase or decrease for a 10-point treatment effect

Explanation

**Given info:**

The power of test for two tailed test with

**b.**

To determine

**To explain:** Whether the power will increase or decrease if alpha is changed to

**c.**

To determine

Whether the power will increase or decrease in one-tailed test.
