The Shoe Store manufactures athletic shoes. The company wants to establish a p-chart to monitor the production process using Z = 3.00. The company has taken a sample of 50 shoes every 4 hours for a work week of five days. Since the company runs two 8-hour shifts each day, this will result in 20 samples. The sample results are as follows.

Sample	Number of Defectives	Proportion Defective	Sample	Number of Defectives	Proportion Defective
1	0	0.00	11	4	0.08
2	1	0.02	12	1	0.02
3	0	0.00	13	1	0.02
4	3	0.06	14	2	0.04
5	2	0.04	15	2	0.04
6	5	0.10	16	3	0.06
7	3	0.06	17	4	0.08
8	2	0.04	18	1	0.02
9	1	0.02	19	5	0.10
10	0	0.00	20	2	0.04
