^ What are the upper AND lower control limits?
Auto pistons at Wenming Chung's plant in Shanghai are produced in a forging process, and the diameter is a critical factor that must be controlled. From sample sizes of 10 pistons produced each day, the mean and the range of this diameter have been as follows: e) If the true diameter mean should be 155mm and you want this as your center (nominal) line, what are the new UCL and LCL ? Upper Control Limit (UCLx)=mm (round your response to two decimal places)
