# Question

Consider the data in Exercise 7.52. Suppose we wish to define a new inspection unit of four tape decks.

(a) What are the center line and control limits for a control chart for monitoring future production based on the total number of defects in the new inspection unit?

The new inspection unit is n = 4 cassette decks. A c chart of the total number of nonconformities per inspection unit is appropriate.

(b) What are the center line and control limits for a control chart for nonconformities per unit used to monitor future production.
