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 = 1.64 lb. a) For the given sample size, the control limits for 3-sigma x chart are: Upper Control Limit (UCL-) = 61.437 lb. (round your response to three decimal places). Lower Control Limit (LCL;) = Ib. (round your response to three decimal places).

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 = 1.64 lb.
a) For the given sample size, the control limits for 3-sigma x chart are:
Upper Control Limit (UCL-) = 61.437 Ib. (round your response to three decimal places).
Lower Control Limit (LCL;) = Ib. (round your response to three decimal places).
