Chick$-$n$-$Gravy Dinner Line

The operations manager of a company that produces frozen dinners had received numerous complaints from supermarkets about the company's Chick$-$n$-$Gravy dinners. The manager 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 centred on five defects: underfilled packages, a missing item, spilled$/$mixed items, unacceptable taste, and improperly sealed packages.

Next, she took $800$ samples of dinners from the two production lines and examined each sample, making note of any defects that she found. A summary of those results is shown in the table below.
