Transcribed Image Text:**Hypothesis Testing Problem**
**Problem Statement:**
Find the P-value for a left-tailed hypothesis test with a test statistic of \( z = -1.72 \). Decide whether to reject \( H_0 \) if the level of significance is \( \alpha = 0.05 \).
**Given:**
- **P-value:** 0.0427 (Round to four decimal places as needed.)
**Conclusion Options:**
Choose the correct answer below:
1. Since \( P \leq \alpha \), reject \( H_0 \).
2. Since \( P > \alpha \), reject \( H_0 \).
3. Since \( P > \alpha \), fail to reject \( H_0 \).
4. Since \( P \leq \alpha \), fail to reject \( H_0 \).
