**Title: Understanding Critical Values in Hypothesis Testing** **Find the Critical Value(s) for a Left-Tailed Z-Test with α = 0.01** In hypothesis testing, the critical value is a threshold to which the test statistic is compared. For a left-tailed z-test with a significance level (α) of 0.01, we need to identify the critical value(s). **The critical value(s) is(are):** Provide the value(s) rounded to two decimal places. Use a comma to separate multiple values if needed. **Draw a Graph of the Rejection Region** Select the correct graph representing the rejection region for the given z-test. **Graph Options:** - **Option A:** A bell curve shaded on the left tail with label α and z-values ranging from -3 to 3. - **Option B:** A bell curve with two tails shaded, showing labels for \(\frac{1}{2}\)α on both sides and z-values from -3 to 3. - **Option C:** A bell curve shaded on the right tail with label α, and z-values from -3 to 3. - **Option D:** A bell curve shaded on the left tail with label α and z-values from -3 to 3. **Instructions:** Click to select your answer(s) based on the correct representation of the rejection region for the given test parameters. By understanding and identifying the correct critical values and corresponding rejection regions, you enhance your ability to carry out statistical hypothesis testing effectively.

**Find the Critical Value(s) for a Left-Tailed Z-Test with α = 0.06** **Task:** Determine the critical value(s) for a left-tailed z-test at a significance level (α) of 0.06. Include a graph with your answer. **Instructions:** - Round to two decimal places as needed. - Use a comma to separate answers if there are multiple values. **Question:** Draw a graph of the rejection region. Choose the correct graph below. **Options:** - **A:** A normal distribution curve is shown, with the left tail shaded in blue, indicating the rejection region. The annotated area is labeled with \( \frac{\alpha}{2} \) and \( \alpha \), distributed across both tails. - **B:** A normal distribution curve with the left tail shaded in blue, labeled with \( \alpha \), indicating the rejection region starting from the left. - **C:** A normal distribution curve with both tails shaded in blue. The left tail is labeled with \( \alpha \), indicating the rejection region. - **D:** A fully shaded blue distribution, with the entire curve indicating the rejection region. **Activity:** Click to select your answer(s). --- When using this content on an educational website, utilize the images and annotations to help students visually understand normal distribution curves and rejection regions in hypothesis testing.
