Refer to Table 56.1 - Factors for Computing Control Chart Limits (3 sigma) for this problem. Auto pistons at Wemming 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: Day Range R (mm) 1 2 3 4 5 Mean x (mm) 154.9 153.2 151.6 157.5 158.6 4.0 4.8 4.1 4.8 4.5 e) If the true diameter mean should be 155 mm and you want this as your center (nominal) line, what are the new UCL; and LCL;? Upper Control Limit (UCLJ) = mm (round your response to two decimal places)
