Question
*This graph shows the rejection regions for both tails*.
- **B.**
*This graph indicates the rejection regions for both the left and right tails*.
- **C.**
*This graph does not indicate the correct region for a right-tailed test*.
- **D.**
*This graph shows the correct rejection region for a right-tailed test*.
**Explanation of Graphs:**
- **Option A:** Shows both tails; however, it may not be appropriate for a right-tailed test.
- **Option B:** Displays shaded regions on both sides of the mean (left and right tails).
- **Option C:** Shows neither tail which does not correspond to a rejection region.
- **Option D:** Illustrates the correct shaded region on the right side of the graph, suitable for our right-tailed test.
**Conclusion:**

**Objective:**
This lesson aims to determine the critical value(s) and rejection region(s) for a right-tailed z-test with a significance level, α, of 0.01. The answer will include an appropriate graph that visually represents the rejection region.
**Problem Statement:**
Find the critical value(s) and rejection region(s) for the type of z-test with a level of significance, α, of 0.01.
*Given:* Right-tailed test, α = 0.01
---
**Steps to Determine Critical Value(s):**
1. **Identify the Critical Value:**
* The critical value(s) is/are z = _____.
* (Note: Round to two decimal places as needed. Use a comma to separate answers as needed.)
2. **Select the Rejection Region:**
Choose the correct choice below and, if necessary, fill in the answer box to complete your choice. (Round to two decimal places as needed.)
- A. The rejection regions are z < _____ and z > _____.
- B. The rejection region is z < _____.
- C. The rejection region is z > _____.
**Example of Correct Rejection Region Graphs:**
Choose the correct graph of the rejection region below.
- **A.**
*This graph shows the rejection regions for both tails*.
- **B.**
*This graph indicates the rejection regions for both the left and right tails*.
- **C.**
*This graph does not indicate the correct region for a right-tailed test*.
- **D.**
*This graph shows the correct rejection region for a right-tailed test*.
**Explanation of Graphs:**
- **Option A:** Shows both tails; however, it may not be appropriate for a right-tailed test.
- **Option B:** Displays shaded regions on both sides of the mean (left and right tails).
- **Option C:** Shows neither tail which does not correspond to a rejection region.
- **Option D:** Illustrates the correct shaded region on the right side of the graph, suitable for our right-tailed test.
