please solve for both UCL AND LCL i will like !

Refer to Tabie S5.1 - Factocs for Computing Control Chart Limits (3 sigma) for this problem. Auto pistons at Wemming Chung'n plant in Shanghal are produced in a forging process, and the diameter is a critcal tactor that must be controlled. From aampie sites of to pitions produced each day, the mean and the rapge of this diameter have been as follows each day, the mean and the nange of this diametar have been as follows: a) What is the value of x ? x=155.16mm (round your response fo ho decimal places) b) What is the value of R ? R=4.44mm (round your response to two decimal placos): c) What are the UCL; and LCL, using 3-sigma? Upper Control Limit (UCL)=mm (round your responso to two decimal paces)
