Consider two independent random samples with the followingresults:
n1=532x1=390   
n2=730x2=139
Use this data to find the 90% confidence interval for the truedifference between the population proportions.
Step 1 of 3: Find the point estimate that should be used inconstructing the confidence interval. Round your answer to threedecimal places.
Step 2 of 3: Find the margin of error. Round your answer to sixdecimal places.
Step 3 of 3: Construct the 90% confidence interval. Round youranswers to three decimal places.
