3. 1 4 I T 5 I G 1. 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 Mean x Range R (mm) (mm) 1 154.9 4.2 2 153.2 4.4 3 151.6 4.3 4 153.5 4.8 5 156.6 4.7 a) [2 pts] What is the value of x? decimal places). mm (round your response to two b) [2 pts] What is the value of R? places). mm (round your response to two decimal c) [4 pts] What are the lower and upper control limits of the x-bar chart?
