Textbook Problem

If a researcher conducted a hypothesis test with an alpha level of α = .02, what z-score values would form the boundaries for the critical region?

To determine
The value of the z-score for the two tailed test with α=0.02.

Explanation

The critical region for the two tailed test is 0.022=0.01

From the z-tables, the value of the critical region at α=0.01, the rejection regions are z=2.33 and z=2
