Refer to Table 561. Factors for Computing Control
Refer to Table 561. Factors for Computing Control Chart Limits (3 sigmafor this problem 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 1 2 3 4 5 Mean (mm) 158.9 1532 1556 153.5 156,6 Range R (mm) 44 48 41 5.0 43 a) What is the value of x? 8= mm (round your response to two decimal places) b) What is the value of R? R=11 mm (round your response to two decimal places). What are the UCL, and L.CL; using 3-sigma? Upper Control Limit (UCL ) - U mm (round your response to two decimal places). Lower Control Limit (LCL) = 0 mm (round your response to two decimal places) d) What are the UCLR and LCLR using 3 sigma? Upper Control Limit (UCLA) = mm (round your response to two decimal places) Lower Control Limit (LCLR) = mm (round your response to two decimal places) e) If the true diameter mean should be 155 mm and you want this as your center (nominal) ine, what are the new UCL, and LCL) Upper Control Limit (UCL) = 0 mm (round your response to ho decimal places) Lower Control Limit (LCL;) = mm (round your response to two decimal places) Enter your answer in each of the answer boxes
