Chapter 6, Section 1-CI, Exercise 011

Use the normal distribution to find a confidence interval for a proportionpgiven the relevant sample results. Give the best point estimate forp, the margin of error, and the confidence interval. Assume the results come from a random sample.

A 99% confidence interval forpgiven thatp^=0.41

andn=550

.

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.
