8. The Jammin' Shoe Company manufacturers athletic shoes. The company wants to establish a control chart to monitor the production process using a 99.73% confidence level. The company has decided to monitor the process based on examining 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 Defective Shoes	Sample	Number of Defective Shoes
1	0	11	4
2	1	12	1
3	0	13	1
4	3	14	2
5	2	15	2
6	5	16	3
7	3	17	4
8	2	18	1
9	1	19	5
10	0	20	2

Construct a control chart to monitor this process. Is the process in statistical control? Explain.
