Use the normal distribution to find a confidence interval


On this problem I only need the margin or error and the confidence interval.

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 90% confidence interval for P given that P(this p has a little carrot top over it)=0.38 and n=525

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=0.38

margin of error= +/- _______________

The 90% confidence interval is________ to __________
