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 99%  confidence interval for P  given that  ^P = 0.36 and n = 475

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

point estimate =

margin of error = + (the + sign has a line under it)

The 99%  confidence interval is  ______ to ________
