Question

Determine the critical value(s) for a one-mean z-test. For each exercise, draw a graph that illustrates your answer.

A two-tailed test with$\alpha =0.10$

Short answer

The graph drawn is

Step-by-step solution

Step 1. Given

A two tailed test with$\alpha =0.10$.

Step 2. Explanation

For the two-tailed test at alpha = 0.10 , from the normal area tables the critical values are z_{0} = - 1.645 and z 0 =1.645. This was shown in the graph as follows:
