3 3 15 3
4 7 16 4
5 6 17 10
6 8 18 9

8 4 20 5
9 8 21 8
10 6 22 6
11 5 23 7
12 12 24 9

a) construct a "c" chart for the number of items per day that are returned for rework. do you think that the process is in a state of statistical control?

b) should the owner of the dry-cleaning store take action to investigate why 12 items were returned for rework on day 12? explain. would your answer change if 20 items were returned for rework on day 2?

c) on the basis of the results in (a), what should the owner of the dry-cleaning store do to reduce the number of items per day that are returned for rework?
