Question

answer part 3

**Hypothesis Testing Guide** Suppose you perform the hypothesis test \( H_0: \mu = 25 \) versus \( H_1: \mu \neq 25 \). The population variance, \( \sigma^2 \), is known. The sample size is \( n = 53 \). Assume the significance level is 0.01. ### Part 1: **1) Selecting the Test Statistic:** - Determine whether to use \( z \) or \( t \) to find the critical value. - **Selection made**: \( z \) is chosen. ### Part 2: **2) Choosing the Critical Region:** - Identify the correct critical region from the given options. - **Selection made**: Reject \( H_0 \) if \( z < - z_{\alpha/2} \) or \( z > z_{\alpha/2} \). ### Part 3: **3) Identifying Critical Values:** - Identify the critical value(s). If there are multiple critical values, separate them using commas. If using \( z \), round to 2 decimals; if using \( t \), round to 3 decimals. **Hint:** Check if you used the correct number of decimals. If you selected a region with 2 sides, did you provide 2 critical values? - **Input Prompt**: Enter a list of integer or decimal numbers.
