Refer to Table S6.1 - Factors for Computing Control Chart Limits 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 = 1.54 lb.
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 (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).
