Use a comma to separate answers as needed.)---### Explanation:This problem involves conducting a hypothesis test using a z-test. The test statistic calculated is \( -2.56 \), and we are testing the hypothesis with a significance level (\( \alpha \)) of 0.10.1. **Determine Critical Values:** - Use the standard normal distribution table to find the critical z-values for \( \alpha = 0.10 \).2. **Decision Rule:** - If the test statistic falls into the critical region (beyond the critical z-value), reject the null hypothesis \( H_0 \). Otherwise, fail to reject \( H_0 \).You can access the standard normal distribution tables through the links provided to find the necessary critical values for the analysis.
