### Hypothesis Testing Example **Problem Statement:** The test statistic of \( z = -2.45 \) is obtained when testing the claim that \( p = 1/4 \). **Steps to Solve:** **a. Finding the Critical Value(s):** Using a significance level of \( \alpha = 0.05 \), find the critical value(s). - Instructions: Use the standard normal distribution table to find the critical value(s). For a two-tailed test with \( \alpha = 0.05 \), look for the values in the table that correspond to 0.025 in each tail. **b. Decision Making:** Should we reject \( H_0 \) or should we fail to reject \( H_0 \)? 1. The critical value(s) is/are \( z = \) - (Enter the critical values rounded to two decimal places. Use a comma to separate answers as needed.) 2. Choose the correct conclusion below: - **A.** Reject \( H_0 \). There is sufficient evidence to warrant rejection of the claim that \( p = 1/4 \). - **B.** Reject \( H_0 \). There is not sufficient evidence to warrant rejection of the claim that \( p = 1/4 \). - **C.** Fail to reject \( H_0 \). There is sufficient evidence to warrant rejection of the claim that \( p = 1/4 \). - **D.** Fail to reject \( H_0 \). There is not sufficient evidence to warrant rejection of the claim that \( p = 1/4 \). **Additional Resources:** - [Click here to view page 1 of the standard normal distribution table.](#) - [Click here to view page 2 of the standard normal distribution table.](#) **Note:** Analyze the provided values against the standard normal distribution table to determine the appropriate critical values and make a justified conclusion based on these values.
