Please answer B.

Please answer B. Refer to Table S6.1 - Factors

Refer to Table S6.1 - Factors for Computing Control Chart Limits (3 sigma) for 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 Range R (mm) Mean x (mm) 154.9 155.2 1 4.0 4.4 2 3 151.6 4.1 4 157.5 154.6 5.0 4.7 5 a) What is the value of x?
