Question
**Title: Finding Critical Values and Rejection Regions for Z-Test** --- **Objective:** Determine the critical value(s) and rejection region(s) for a right-tailed Z-test with a significance level of \(\alpha = 0.005\). A graph must be included to illustrate the rejection region(s). --- **Instructions:** 1. **Calculate the Critical Value(s):** The critical value(s) are \( z = \_\_\_\) (Round to two decimal places as needed. Use a comma to separate answers if there are multiple critical values.) 2. **Select the Correct Rejection Region:** Choose the appropriate rejection region and enter the necessary value in the provided answer box. (Round to two decimal places as needed.) - **A.** The rejection region is \( z > \_\_\_ \). - **B.** The rejection region is \( z < \_\_\_ \). - **C.** The rejection regions are \( z < \_\_\_ \) and \( z > \_\_\_ \). 3. **Choose the Correct Graph:** Select the correct graph that depicts the rejection region(s). - **A.** ![Option A](URL) *Graph description: A normal distribution curve with the left and right tails shaded in light blue.* - **B.** ![Option B](URL) *Graph description: A normal distribution curve with the right tail shaded in light blue.* - **C.** ![Option C](URL) *Graph description: A normal distribution curve with both tails shaded in light blue.* - **D.** ![Option D](URL) *Graph description: A normal distribution curve with the area under the curve (not tails) shaded in light blue.* --- **Note**: The images provided visually represent the options for rejecting the null hypothesis based on the Z-test. Be attentive to match the correct critical value and region with its corresponding graphical representation. --- **Conclusion:** Upon computing the critical value, selecting the appropriate rejection region, and matching it with the correct graph, you will effectively determine the statistical significance of your Z-test result at \(\alpha = 0.005\). --- This exercise assists in understanding hypothesis testing, critical values, and rejection regions using Z-tests, an essential component of statistical analysis.
