**Critical Values for Quick Reference During This Activity**

A table provides critical values for different confidence levels:

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

**Example Calculation**

In a poll of 1000 randomly selected voters in a local election, 453 voters were in favor of school bond measures.

1. **What is the sample proportion \( \hat{p} \)?**
   - Enter your answer in the format: Ex: 0.123

2. **What is the margin of error \( m \) for the 90% confidence level?**
   - Enter your answer in the format: Ex: 0.123
