Consider two independent random samples with the following results:

n1=578

n2=593

pˆ1=0.59  

pˆ2=0.68

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

Step 1 of 3: Find the point estimate that should be used in constructing the confidence interval.
