![### Confidence Level and Critical Values
The table below shows the critical values associated with different confidence levels:
| Confidence Level | Critical Value \( z^* \) |
|------------------|--------------------------|
| 0.90 | \( z^* = 1.645 \) |
| 0.95 | \( z^* = 1.960 \) |
| 0.99 | \( z^* = 2.576 \) |
### Context Example
In a poll of 1,000 randomly selected voters in a local election, 59 voters were against school bond measures.
#### Calculation Task
To find out what the 95% confidence interval is, use the critical value of 1.960 for a 95% confidence level. Fill in the calculated values in the provided format:
\[
[\text{smaller value}, \text{larger value}]
\]
This interval provides an estimate range for the proportion of the overall population that is against the school bond measures based on the sample data.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F302e2d83-124e-4749-a014-0416d12786b1%2F98350ec8-232b-40c3-8f0d-b4de03b79242%2F3cgfnc8_processed.png&w=3840&q=75)
