Q. 9.43 - 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 left - tailed test with$\alpha = 0.01$

Step-by-Step Solution

Answer

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

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

Step 1. Given

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

Step 2. Graph

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

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