Refer to Table 56.1 - Factors for Computing Control Chart Limits 3 sioma) for this problem. Question Help 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) Mean x (mm) 154.9 1512 1516 153.5 158.6 a) What is the value of x? x 153.96 mm (round your response to two decimal places). b) What is the value of R? R 4-44 mm (round your response to two decimal places). c) What are the UCL, and LCL; using 3-sigma? Upper Control Limit (UCL) = mm (round your response to two decimal places)
