Chick-n-Gravy Dinner Line

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 generat-
ing the complaints. The majority of complaints centered on five
iefects: underfilled packages, a missinq item, spillslmixed items,
Inacceptable 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 that she
found. A summary of those results is shown in the table.

The data resulted from inspecting approximately 800 frozen
dinners. What should Ann recommend to the manaoer?
