R=mm (round your response to two decimal places). c) What are the UCxand LLxusing 30 ? Upper Control Limit (UCL)=mm (round your response to two decimal places). Lower Control Limit (LCL)=mm (round your response to two decimal places). d) What are the UCLR and LCLR using 3 ? Upper Control Limit (UCLR)=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 155mm and you want this as your centre (nominal) line, what are the new UCL and LCL? Upper Control Limit (UL)=mm (round your response to two decimal places). Lower Control Limit (LCLx)=mm (round your response to two decimal places)
