At fruits and such, a local fruit concentrate manufacturer, frozen orange juice is packed in 12-oz cardboard
Question:
At fruits and such, a local fruit concentrate manufacturer, frozen orange juice is packed in 12-oz cardboard cans. These cans are formed on a machine by spinning them from preprinted cardboard stock and attaching two metal lids, one for the top and one for the bottom. After filling the container is carefully inspected. The inspector test how well the strip to open the can operates. If a strip breaks the can is considered non-conforming and unusable. Other packing non-conformities includes improper crimps holding the lids to the cardboard tube or poorly sealed lids. Fill rates are carefully checked to ensure that the containers truly contain 12-oz. Inspectors also check the cosmetics of the can. Incorrectly wrapped cans or crooked labels are considered non-conforming and unusable.
An np chart for tracking unusable nonconformities needs to be established to track the level of nonconformities produced on a daily basis. The first 30 subgroups of size n=50 are founded on figure 1
Use the total number of defectives to create the np chart. How is the process currently performing? What is the process capability?
