Refer to Table 56.1-Factors for Computing Control Chart Limits (3 sigma) for this problem Thirty-five samples of size 7 each were taken from a fertilizer-bag-filing machine at Panos Kouvelis Lifelong Lawn Ltd. The results were: Overall mean 60.75 lb. Average range R = 1.64 lb. a) For the given sample size, the control limits for 3-sigma x chart are: Upper Control Limit (UCL;) Lower Control Limit (LCL;) b. (round your response to three decimal places). b. (round your response to three decimal places). b) The control limits for the 3-sigma R-chart are: Upper Control Limit (UCLA) b. (round your response to three decimal places). b. (round your response to three decimal places). Lower Control Limit (LCL)
