Refer to Table S6.1 - Factors for Computing Control Chart Limits (3 sigma) for this problem. Thirty-five samples of size 7 each were taken from a fertilizer-bag-filling machine at Panos Kouvelis Lifelong Lawn Lid. The results were: Overall mean =57.75lb; Average range R=1.54lb. a) For the given sample size, the control limits for 3 -sigma x chart are: Upper Control Limit (UCL)= Ib. (round your response to three decimal places). Lower Control Limit (LCLx)= 1b. (round your response to three decimal places). b) The control limits for the 3-sigma R-chart are: Upper Control Limit (UCLR)= b. (round your response to three decimal places). Lower Control Limit (LCLR)= lb. (round your response to three decimal places)
