Refer to Table S6.1 - Factors for Computing Control Chart Limits (3sigma)1 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 = 60.75lb.; Average range R=1.64lb. 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). Refer to Table S6.1 - Factors for Computing Control Chart Limits (3sigma)1 for this problem.
