Q. 9.45 - Elementary Statistics

Question

In each of Exercises 9.41-9.46 ,determine the critical values for a one-mean z-test. For each exercise, draw a graph that illustrates your answer

A right- tailed test with$\alpha = 0.01$

Step-by-Step Solution

Answer

A Right -tailed test with $\alpha = 0.01$

In the right tail test that $\alpha = 0.01$, from normal local tables values are significant ${\mathrm{z}}_0 = 2.33$.

Step 1. Given

A right -tailed test with $\alpha = 0.01$

Step 2. Graph

A Right -tailed test with$\alpha = 0.01$.

In the right tail test that $\alpha = 0.01$, from normal local tables values are significant ${\mathrm{z}}_0 = 2.33$.

The graph is shown below:
