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.
(b) Are the sample sizes large enough for the Central Limit Theorem to apply?
mean = 0.260 standard error = 0.071 (b) Are... View the full answer
