Suppose a process has been monitored daily for the last ten days and the number of machine failures each day was noted. The results follow: Day Number: 1 2 3 4 5 6 7 8 9 10 Number of Failures: 8 9 6 10 12 4 9 11 9 12 Compute control limits for a c-chart that monitors the average number of machine failures per day. Is the process in a state of control?
