The overall average on a process you are attempting to monitor is 50.0 units. The process population standard deviation is 1.84, Sample size is given to be 4. a) Determine the 3-sigma x-chart control limits. Upper Control Limit (UCL- UL ) = units (round your response to two decimal places). Lower Control Limit (LCLx)= units (round your response to two decimal places). b) Now determine the 2-sigma x-chart control limits. Upper Control Limit (UCL- U^)= units yround your rosponso to two decimal places). Lower Control Limit (LCL- )= units (round your responso fo two docimal places). How do the control limits change? A. The control limits are tighter for the 2-sigma x-chart than for the 3-sigma x-chart. B. The control limits are tighter for the 3-sigma x-chart than for the 2-sigma x-chart. C. The control limits for the 2-sigma x-chart and for the 3-sigma x-chart are the same
