I need help finding the upper control limit and lower control limit

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 o 10 pistons produced each day, the mean and the range of this diameter have been as follows: a) What is the value of x ? x=mm(roundyourresponsetotwodecimalplaces). b) What is the value of R ? R=mm(roundyourresponsetotwodecimalplaces). c) What are the UCLand LCLx - using 3-sigma? Upper Control Limit (UCL)=mm (round your response to two decimal places).
