Upper Contro Limit (UCL)= mon (round yeur moponce so wo dech miteax) Auto pistons at Wemming Chung's plant in Shanghal are produced in a forging process, and the diametor 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. mm (round your response to two decimal places). b) What is the value of R? R=4.44mm (round your response to two decimal places). c) What are the UCL; and LCLx using 3-sigma? Upper Control Limit (UCL UCx)=157.33mm (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? x= mm (round your response to two decimal places). b) What is the value of R ? R=4.44mm (round your response to two decimal placns). c) What are the UCL; and LCL. using 3-sigma? Upper Control Limit (UCL, )=16733mm (round your response to two docimal places). Lower Control Limit (LCly^)=154.68mm (round your response to two decimat places) Upper Control Limit (UCL URR ) 7.8 igkmm (round your response to fwo docimat places). Lower Control Limit (LCLR)=99mm (round your response to two decirial places). e) If the true diameter mean should be 155mm and you want this as yout center (nominal) line, what are the new uCL. and LCLx ? Upper Control Limit (UCLx)=mm (round your response to two decimar places)
