Refer to Table S6.1 - Factors for Computing_Control Chart Limits (3 sigma) for this problem. 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: a) What is the value of x ? x=153.96mm(roundyourresponsetotwodecimalplaces). b) What is the value of R ? R=4.48mm(roundyourresponsetotwodecimalplaces). c) What are the UCL and LCL using 3-sigma? Upper Control Limit (UCL)=mm (round your response to two decimal places). Lower Control Limit (LCLx)=mm (round your response to two decimal places). d) What are the UCLR and LCLR using 3-sigma? Upper Control Limit (UCLR)=7.96mm (round your response to two decimal places). Lower Control Limit (LCLR)=mm (round your response to two decimal places)
