Use the normal distribution to find a confidence interval for a difference in proportions p1-p2 given the relevant sample results. Assume the results come from random samples.
A 99% confidence interval for p1-p2 given that p^1=0.20 with n1=60 and p^2=0.35 with n2=100
Give the best estimate for p1-p2, the margin of error, and the confidence interval.
Round your answer for the best estimate to two decimal places and round your answers for the margin of error and the confidence interval to three decimal places.
a) Find Best Estimate:
b) Find Margin of Error
c) Find Confidence Interval
