**Educational Material on Determining Critical Values and Rejection Regions in a T-Test** This instructional module explores how to find the critical value(s) and rejection region(s) for a specified t-test, considering the level of significance (\(\alpha\)) and sample size (\(n\)). --- **Instructions:** 1. **Problem Statement:** - Find the critical value(s) and rejection region(s) for the indicated t-test. - Parameters: - Two-tailed test - Level of significance (\(\alpha\)): 0.01 - Sample size (\(n\)): 23 2. **Process:** - To achieve the above, click the icon provided to view the t-distribution table. 3. **Solution Step:** - **Critical Value(s):** - The critical value(s) is/are: **4** - (Note: Round to the nearest thousandth as necessary. Use a comma to separate multiple answers if needed.) - **Rejection Region:** - Determine which of the following options correctly represents the rejection region, using the critical value: - **Option A:** \( t < \_ \) and \( t > \_ \) - **Option B:** \( t < \_ \) - **Option C:** \( t > 4 \) - **Option D:** \(\_ < t < \_\) - Based on the critical value provided, the correct rejection region is: **C. \( t > 4 \)** **Note:** It is crucial to round the numerical answers to the nearest thousandth as needed when calculating the critical values and specifying the rejection regions. --- This material is designed to reinforce your understanding of hypothesis testing and statistical inference using the t-distribution. Be sure to consult relevant statistical tables and resources to ensure precision in calculations.
