e) If the true diameter mean should be 155 mm and you want this as your center (nominal) line, what are the new

UCLx and LCLx?

Upper Control Limit

(UCLx) = ? mm (round your response to two decimal places).

Lower Control Limit

(LCLx) =?

mm (round your response to two decimal places).

Auto pistons at Wemming Chung & 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. Mean (mm) 1549 153.2 Range R (mm) 44 Day 1 2 3 4 5 5.0 153.5 158.6 a) What is the value at 1-1 mm iraund your response to nao decimal places). b) What is the value of R? R-mm (round your response to two decimal places). c) What are the UCL and LCL, using 3-sigma? Upper Contro Limit UCL = _ min (round your response to to decinal pieces) Lower Contro Limit (LCD) mm (round your response to two decimal places). d) What are the UCL and LCLR using 3-sigure? Upper Contro Limit UOLp) = mm (round your response to two decimal places
