The operations manager of a firm that produces frozen dinners had received numerous complaints from supermarkets about the firm's Chick-n-Gravy dinners. The manager then asked her assistant, Ann, to investigate the matter and to report her recommendations. Ann's first task was to determine what problems were generating the complaints. The majority of complaints centered on five defects: underfilled packages, a missing label, spills/mixed items, unacceptable taste, and improperly sealed packages. Next, she took samples of dinners from the two production lines and examined each sample, making note of any defects she found. A summary of those results is shown in the table below. The data resulted from inspecting approximately 800 frozen dinners. What should Ann recommend to the manager?
