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

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

**Poll Analysis:**

In a poll of 1,000 randomly selected voters in a local election, 326 voters were against fire department bond measures.

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

- **Question 2:** What is the margin of error \( m \) for the 99% confidence level? *(Example: 0.123)*

These details can be used to calculate confidence intervals and assess the reliability of the polling results.
