Refer to Table S6.1 - Factors for Computing Control Chart Limits ( 3 sigma) for this problem. a) For the given sample size, the control limits for 3 -sigma x chart are: Upper Control Limit (UCL)=lb. (round your response to three decimal places). Lower Control Limit (LCLx)= lb. (round your response to three decimal places). b) The control limits for the 3-sigma R-chart are: Upper Control Limit (UCLR)= lb. (round your response to three decimal places). Lower Control Limit (LCLR)= lb. (round your response to three decimal places)
