### Confidence Level and Critical Value Reference

The table below provides critical values for quick reference during this activity:

| Confidence Level | Critical Value (z*) |
|------------------|----------------------|
| 0.90             | 1.645                |
| 0.95             | 1.960                |
| 0.99             | 2.576                |

**Jump to level 1**

**Poll Data:**

In a poll of 1000 randomly selected voters in a local election, 210 voters were in favor of school bond measures.

1. **What is the sample proportion \(\hat{p}\)?**  
   - Example: 0.123  

2. **What is the margin of error \(m\) for the 95% confidence level?**  
   - Example: 0.123
