Quizplus · Accepted Answer

Maxwell is comparing the proportion of employees with up-to-date certifications between the north-east and southern divisions, expecting the north-east division to have a higher rate. Choice B correctly represents this as a comparison of proportions (p) where the proportion in the north-east division (p1) is greater than the southern division (p2).
