**Hypothesis Testing Scenario:** Suppose you want to test the claim that \( \mu > 25.6 \). Given: - Sample size (\( n \)) = 47 - Level of significance (\( \alpha \)) = 0.1 **Question:** When should you reject the null hypothesis \( H_0 \)? **Options:** - **A.** Reject \( H_0 \) if the standardized test statistic is greater than 2.33. - **B.** Reject \( H_0 \) if the standardized test statistic is greater than 1.28. (Correct Option) - **C.** Reject \( H_0 \) if the standardized test statistic is greater than 2.575. - **D.** Reject \( H_0 \) if the standardized test statistic is greater than 1.645. **Explanation:** The correct critical value for a one-tailed test at a 0.1 significance level is approximately 1.28. Therefore, the null hypothesis should be rejected if the test statistic exceeds this value.
