Consider random samples of size 86 drawn from population A with proportion 0.42 and random samples of size 60 drawn from population B with proportion 0.16.

(a) Find the mean and standard error of the distribution of differences in sample proportions, p A - p B

Round your answer for the mean to two decimal places and your answer for the standard error to three decimal places.
