Question
**Title: Finding Critical Values and Rejection Regions for a Right-tailed Z-Test**

---

**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.**
  ![Graph A](link)
  *This graph shows the rejection regions for both tails*.

- **B.**
  ![Graph B](link)
  *This graph indicates the rejection regions for both the left and right tails*.

- **C.**
  ![Graph C](link)
  *This graph does not indicate the correct region for a right-tailed test*.

- **D.**
  ![Graph D](link)
  *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:**
After identifying the critical value and appropriate rejection region
