 Auto pistons at Wemming​ Chung's plant in Shanghai are produced in a forging​ process, and the ... 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​ followsa) What is the value of x? - mm (round your response to two decimal places) b) What IS the value of R? mm (round your response to two decimal places). c) What are the UCL- and LCL- using 3.sigma? Upper Control Limit (UCL-) = C] mm (round your response to two decimal places). Lower Control Limit (LCL-) = mm (round your response to two decimal places). d) What are the UCLR and LCLR using 3-sigma? Upper Control Limit (UCLR) = mm (round your response to two decimal places) Lower Control Limit (LCL R) = mm (round your response to two decimal p/aces)_ 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 (UCL-) = mm (round your response to avo decimal places). Lower Control Limit (LCL- ) = mm (round your response to two decimal places).

 Quote from: Catracho (3 years ago)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 (UCL-) = mm (round your response to avo decimal places). Lower Control Limit (LCL- ) = mm (round your response to two decimal places).155 + (0.308)*4.56 = 156.40 UPPER155 - (0.308)*4.56 = 153.60 LOWER
