Jeffery surveyed 50 randomly selected workers at a factory. He collected data about the individual output of a worker on an average day. The results are shown using the boxandwhiskel' plot. 04::0 I] 10 20 30 4|] 50 60 70 so 90 100 What percent of workers have output more than 7'0 units? Find intersections and unions of the following given sets. Use the Venn diagram to find AUB, Cn D, and (A UC) UD.
