An automotive parts supplier assesses the usability and quality of the door locks that they provide. The locks are manufactured at three different plants. The production manager wants to determine whether the plant affects the final product. The production manager collects data on locks from each plant, and gives a usability and quality rating. Data are found in the file Car Lock Ratings.

saying that they selected 20 at random and found 2 faulty, an error
rate of 10%. Was the customer justified in returning the shipment
