Refer to the table Factors for Computing Control Chart Limits ( 3 sigma). for this problem. Your supervisor, Lisa Lehmann, has asked that you report on the output of a machine on the factory floor. This machine is supposed to be producing optical lenses with a mean weight of 50 grams and a range of 3.5 grams. The following table contains the data for a sample size of n=6 taken during the past 3 hours: Set the control limits for this process for the x-chart when the machine is working properly. UCLx=51.69grams(roundyourresponsetotwodecimalplaces).LCLx=grams(roundyourresponsetotwodecimalplaces).
