![**Current Attempt in Progress**
Use the normal distribution to find a confidence interval for a proportion \( p \) given the relevant sample results. Give the best point estimate for \( p \), the margin of error, and the confidence interval. Assume the results come from a random sample.
A 95% confidence interval for \( p \) given that \( \hat{p} = 0.41 \) and \( n = 450 \).
Round your answer for the best point estimate to two decimal places, and your answers for the margin of error and the confidence interval to three decimal places.
- Best point estimate = [input box]
- Margin of error = ± [input box]
- The 95% confidence interval is [input box] to [input box]
