The process population standard deviation is 1.84 Sample size is given to be 4 a) Determine the 3-sigma x-chart controllimits. 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 controllimit Upper Control Limit (UCL) - units (round your response to two decimal places) Lower Control Limit (LCL) - units fround your response to two decimal places) How do the control limits change? O 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. O C. The control limits for the 2-sigma x-chart and for the 3-sigma x-chart are the same. VI
