Refer to the table Factors for Computing Control Chart Limits (3sigma)1 for this problem. 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: a) What are the x-chart control limits when the machine is working properly? UCLx=LCLx=grams(roundyourresponsetotwodecimalplaces).grams(roundyourresponsetotwodecimalplaces). Choose the correct graph of the sample data for the x-chart. b) What are the R-chart control limits when the machine is working properly? UCLR=LCLR=grams(roundyourresponsetotwodecimalplaces).grams(roundyourresponsetotwodecimalplaces). Choose the correct graph of the sample data for the R-chart. A. B. c. c) What seems to be happening?
