Question: Only need part B, upper and lower control limit. Refer to Table S6.1 - Factors for Computing Control Chart Limits (3 sigma) for this problem.
Only need part B, upper and lower control limit.

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 =57.75lb;; Average range R=1.64lb. a) For the given sample size, the control limits for 3 -sigma x chart are: Upper Control Limit (UCLx)= lb. (round your response to three decimal places). Lower Control Limit (LCL)= Ib. (round your response to three decimal places). b) The control limits for the 3-sigma R-chart are: Upper Control Limit (UCLR)= Ib. (round your response to three decimal places)
