It appears that you have uploaded a photo of a math/statistics problem related to a confidence interval for a proportion. The text says:

"There is an approximately 95% chance that between \_\_\_\_ and \_\_\_\_ teenagers in the sample will not have checking accounts."

This is likely asking you to compute a 95% confidence interval for a sample proportion.

To calculate this, you'd typically use the formula for a confidence interval:

\[
\hat{p} \pm Z \cdot \sqrt{\frac{\hat{p}(1 - \hat{p})}{n}}
\]

Where:
- \(\hat{p}\) is the sample proportion (i.e., the proportion of teenagers without checking accounts).
- \(Z\) is the Z-score for a 95% confidence level, which is approximately 1.96.
- \(n\) is the sample size.

You'll need to plug in the values for \(\hat{p}\) and \(n\) from the problem to calculate the interval.

Would you like to provide the sample size (\(n\)) and the sample proportion (\(\hat{p}\)) so I can help you complete this calculation?

Here are 5 follow-up questions related to confidence intervals:
1. What is the sample size for this particular problem?
2. How do you calculate the sample proportion from given data?
3. Why is the Z-score 1.96 for a 95% confidence level?
4. What does the margin of error represent in a confidence interval?
5. How would you interpret the confidence interval once calculated?

**Tip:** Confidence intervals provide a range of values within which we expect the true population parameter to fall, based on the sample data.

There is an approximately 95% chance that between ___ and ___ teenagers in the sample will not have checking accounts.

Learn how to calculate a 95% confidence interval for the proportion of teenagers without checking accounts using the formula for confidence intervals of proportions. This problem applies key statistical concepts like sample proportion and the Z-score for confidence levels.
