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 Ltd. The results were: Overall mean = 60.75 lb.; Average range R = 1.78 lb. a) For the given sample size, the control limits for 3-sigma x chart are: Upper Control Limit (UCL) = 61.496 lb. (round your response to three decimal places). X Definition Lower Control Limit (LCL) = 60.004 lb. (round your response to three decimal places). b) The control limits for the 3-sigma R-chart are: Lower Range, Upper Control Limit (UCL) = lb. (round your response to three decimal places).
