Using control charts for number of nonconformities, can you conclude that the process is in statistical control? What center line and control limits would you recommend for controlling future production?

b.) Suppose we wish to define a new inspection unit of 15 painted panels, what are the center line and control limits for monitoring future production based on the total number of defects?

c.) A painted panel measures 2 ft. x 2 ft. What are the center line and control limits appropriate for a control chart for average nonconformities per square foot which can be used to monitor future production?

III. (14pts) An inspector takes samples of 10 painted panels from a painting line at random intervals. She records the number of minor defects in each sample
