### Current Attempt in Progress

Use the t-distribution to find a confidence interval for a mean μ given the relevant sample results. Give the best point estimate for μ, the margin of error, and the confidence interval. Assume the results come from a random sample from a population that is approximately normally distributed.

A 95% confidence interval for μ using the sample results \( \overline{x} = 81.4 \), \( s = 7.6 \), and \( n = 42 \).

Round your answer for the point estimate to one decimal place, and your answers for the margin of error and the confidence interval to two decimal places.

- Point estimate: \( \overline{x} \)
- Margin of error: \( E \)

The formula for the confidence interval is \( \overline{x} \pm E \).

#### Input fields:

- Point estimate = \[ \]
- Margin of error = \[ \]
- The 95% confidence interval is \[ \] to \[ \]
