The overall average on a process you are attempting to monitor is 55.0 units. The process population standard deviation is 1.72. Sample size is given to be 16. 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) Now determine the 2-sigma X-chart control limits. Upper Control Limit (UCL)= Lower Control Limit (LCL-) = How do the control limits change? units (round your response to two decimal places). units (round your response to two decimal places). OA. The control limits are tighter for the 3-sigma X-chart than for the 2-sigma X-chart. OB. The control limits are tighter for the 2-sigma X-chart than for the 3-sigma X-chart. OC. The control limits for the 2-sigma x-chart and for the 3-sigma x-chart are the same. The overall average on a process you are attempting to monitor is 55.0 units.
