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.
mean =
standard error=
(b) Are the sample sizes large enough for the Central Limit Theorem to apply?
Yes
or
No
