To draw the p-chart for the nonconforming units.

The coating of the candy bar is currently made by a process that can result in surface cracking. To monitor the process, it was decided to construct a P chart. During four shifts, 30 samples of size 60 were collected, and the results are as follows:

Sample Number	Nonconforming units found	Sample Number	Nonconforming units found
1	2	16	3
2	6	17	4
3	1	18	6
4	3	19	4
5	7	20	3
6	9	21	1
7	2	22	4
8	1	23	3
9	7	24	6
10	2	25	2
11	0	26	3
12	3	27	4
13	1	28	3
14	4	29	6
15	6	30	2

a. Set up the trial control limits for a 3-sigma P chart and plot the data.

b. Comment as to the stability of the process.
