The overall average on a process you are attempting to monitor is 55.0 units. The process population standard deviation is 1.84. Sample size is given to be 16. A) Determine the 3-sigma x -chart control limitsUpper 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 limitsUpper Control Limit (UCL- ) = units (round your response to two decimal places).Lower Control Limit (LCL- ) = units (round your response to two decimal places).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 sameB. 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.
