The results were: Overall mean = 60.75 lb. Average range R = 1.78 lb a) For the given sample size, the controlimits for 3-sigmax chart are: Upper Control Limit (UCL) = b. (round your response to three decimal places) L.ower Control Limit (LC_) = 1to. (round your response to theroo decimal places) b) The controllimits for the 3-sigma R-chartare Upper Control Limit(1.2) - (round your response to three decimal places), Lower Controllimit (LC) - (round your response to three decimal places)
