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: Range R (mm) Day Mean x (mm) 154.9 1512 155.6 157.5 156.6 a) What is the value of ? x= 155.16 mm (round your response to two decimal places). b) What is the value of R?
