The overall average on a process you are attempting to monitor is 55.0 unts. The procesa population standard deviation is 1.72. Sample size is given to be 4 a) Determine the 3-sigma X-chart control limits Upper Control Limit (UCL) -units (round your response to two decimal places) Lower Control Limit (LC) - units (round your response to two decimal places) b) Now determine the 2-sigma x-chart control limits Upper Control Limit (UCL;)-units (round your response to two decimal placea) Lower Control Limit (LCL:)-units (round your response to two decimal plocos), How do the controllimits change? OA. The control limits are tighter for the 3-sigma x-chart than for the 2-sigma X-chart. B. The control limits for the 2-sigma X-chart and for the 3-sigma x chart are the same OC. The controllimits are tighter for the 2-digma Richart van for the 3-sigmax chart Cakto select your answers) The overall average on a process you are attempting to monitor is 55.0 units.
