a)
| control line (CL) = p̅= | 0.051 | ||||
| upper control limit(UCL) =p̅+3*(√(p̅(1-p̅)/n)= | 0.064 | ||||
| lower control limit(LCL) =max(0,p̅-3*(√(p̅(1-p̅)/n))= | 0.038 | ||||
b)Yes because the sample proportion lies within the control limits

Due to the poor quality of various semiconductor products used in its manufacturing process, Microlabratories has decided to develop a QC program. Because of the semiconductor parts, they get from suppliers are either good or defective, Milton Fisher has decided to develop control charts for attributes. The total number of semiconductors in every sample is 200. Furthermore, Milton would life to determine the upper and lower control-chart limits for various values of the fraction defective (p) in the sample taken....
