Problem 4 A sampling of political candidates, 200 randomly chosen from the West and 200 from the East, was classified according to whether the candidate received backing by a national labor union and whether the candidate won. In the West, 116 winners had union backing, and in the East, 142 winners were backed by a national union. a) Estimate the difference between the proportions of union-backed winners in the West versus the East. Use a 95% confidence interval and interpret your results.
