Do not round intermediate results. a) The lower and upper control limits for the R-chart are: LOL = UCL = Does it appear that the process range is out of control? O Yes. There is no point outside the control limits. O No. There is no point outside the control limits. O No. There is at least one point outside the control limits. O Yes. There is at least one point outside the control limits. b) The lower and upper control limits for the -chart are: LCL = UCL = Does it appear that the process mean is out of control? O Yes. There is no point outside the control limits. O No. There is at least one point outside the control limits. O Yes. There is at least one point outside the control limits. O No. There is no point outside the control limits
