Lower Range Siren Refer to Table 56.1-Factor for Computing Control Chart Limits (3 sigma) for this problem Thirty-five samples of size 7 each were taken from a fertilizer-bag-filing machine at Panos Kouvelis Lifelong Lawn Ltd. The results were: Overal mean = 54,75 Ib.: 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) = 55.437 b. (round your response to three decimal places) Defintion Lower Control Limit (LCL ) = 54.063) 15. (round your response to three decimal places). Sample Mean Factor Upper Range b) The control limits for the 3-sigma R-chart are: Az D4 D 3.268 Upper Control Limit (UCLR)-(round your response to three decimal places). 2574 Lower Control Limit (LCR)-1.
