Express the confidence interval 
 in interval form.



Express the answer in decimal format (do not enter as percents). 57.7 5.9

To express the confidence interval in interval form based on the given values:

1. **Point Estimate**: 57.7
2. **Margin of Error**: 5.9

The confidence interval can be calculated as:

- **Lower Bound**: \( 57.7 - 5.9 = 51.8 \)
- **Upper Bound**: \( 57.7 + 5.9 = 63.6 \)

Thus, the confidence interval in interval form is:

\[
(51.8, 63.6)
\]
