a) Determine the 3-sigma x -chart control limits Upper Control Limit (UCL- ) = ____ units (round your response to two decimal places). Lower Control Limit (LCL- ) = _____ units (round your response to two decimal places). B) Determine the 2-sigma x-chart control limits Upper Control Limit (UCL-) = units (round your response to two decimal places). units (round your response to two decimal places). Lower Control Limit (LCL-) = How do the control limits change? A-The control limits for the 2-sigma overbar x-chart and for the 3-sigma x -chart are the same B- The control limits are tighter for the 2-sigma overbar x -chart than for the 3-sigma x -chart. C- The control limits are tighter for the 3-sigma overbar x -chart than for the 2-sigma x -chart.
