b) Lower Control Limit -x = __ (round to nearest three decimal places)

The control limits for 3 sigma R chart are:

c) Upper Control Limit (UCLr) = __ lb. (round to nearest three decimal places)

d) Lower Control Limit (UCLr) = ___ lb (round to nearest three decimal places)

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-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: i Definition X Upper Control Limit (UCL;) = b.
