B & C please C says the critical value for a two tailed sample is :
### Determining Critical Values for Population Standard Deviation Tests **Determine the critical values for these tests of a population standard deviation.** 1. **A right‐tailed test with 15 degrees of freedom at the α = 0.01 level of significance.** 2. **A left‐tailed test for a sample of size n=21 at the α = 0.05 level of significance.** 3. **A two‐tailed test for a sample of size n=24 at the α = 0.01 level of significance.** #### Steps for Calculation: 1. **Click the icon to view a table of critical values for the Chi-Square Distribution.** --- **Solution:** **(a) The critical value for this right‐tailed test is \( 22.307 \).** \ (Round to three decimal places as needed.) **(b) The critical value for this left‐tailed test is \( \_ \).** \ (Round to three decimal places as needed.) --- **Graphical/Diagram Explanation:** *There are no graphs or diagrams present in the provided image.* --- *Use this information to understand how to determine critical values for different types of hypothesis tests involving population standard deviations.* **Additional Resources:** - Textbook - Statcrunch - Ask my instructor *(Note: Ensure to click on the Chi-Square Distribution critical values table icon for more detailed analyses if needed.)*
