Chapter 6, Section 3-D, Exercise 131 Consider random samples of size 56 drawn from population A with proportion 0.70 and random samples of size 74 drawn from population B with proportion 0.60. (a) Find the standard error of the distribution of differences in sample proportions, PA - PR. Round your answer for the standard error to three decimal places. standard error = the absolute tolerance is +/-0.001
