The overall average on a process you are attempting to monitor is 50.0 units. The process population standard deviation is 1.72. Sample size is given to be 5. a) Determine the 3-sigma x-chart control limits. SHOW YOUR STEPS FOR YOUR CALCULATIONS Upper Control Limit (UCLx) = units (round your response to two decimal places). SHOW YOUR STEPS FOR YOUR CALCULATIONS Lower Control Limit (LC_) = _ units (round your response to two decimal places). b) Now determine the 2-sigma x-chart control limits. SHOW YOUR STEPS FOR YOUR CALCULATIONS Upper Control Limit (UCLZ) = units (round your response to two decimal places). SHOW YOUR STEPS FOR YOUR CALCULATIONS Lower Control Limit (LCLx) = units (round your response to two decimal places)
