EMERGENCY PLEEASE !!!

An injection molding process is studied with a pp chart. The number of parts produced per hour varies, so does the sample size. The data shown below summarize the number of parts sampled and the number of defectives observed for 10 hours of operation for the process. (Error tolerance is 0.02 for each value.)

Sample	Sample size	Number of defectives
1	47	2
2	41	2
3	56	3
4	54	1
5	50	4
6	62	3
7	60	5
8	50	3
9	48	2
10	52	1
SUM	520	26

a. (2 points) Calculate the center line of the chart. Center Line: ???

b. (4 points) Calculate the lower and upper control limits for Sample 5. LCL: ?? UCL: ??

c. (2 points) Is sample 5 within control limits? Answer: Yes OR No
