2 Refer to Toble 56.1-Factors for Computing Control Chart Limits (3.gma) for this problem Thirty-five samples of size 7 each were taken from a fertilizer-bag-filling machine at Panos Kouvelis Lifelong Lawn Ltd. The results were: Overall mean = 54.75 ID; Average range R=178 lb. a) For the given sample size, the controllimits for 3-sigma x chart are: Upper Control Limit (UCL ) - ( 15. (round your response to three decimal plucos). Lower Control Limit (.CL)- (round your response to three decimal places) b) The controllimits for the 3-sigma R-chart are: Upper Control Limit (UCLR) - 1b. (round your response to three decimal places) Lower Control Limit (LCLR)=b (round your response to three decimal places)
