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 90% confidence interval forpgiven thatp^=0.39
andn=475
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 =_______________________
Margin of error=_________________.
The 90% confidence interval is______________ to ________________
