Consider two independent random samples with the following results:

n1=578 pˆ1=0.59    n2=593 pˆ2=0.68

Use this data to find the 90%confidence interval for the true difference between the population proportions.

Step 2 of 3:

1-Find the margin of error. Round your answer to six decimal places.

2-Construct the 90% confidence interval. Round your answers to three decimal places.
