The overall average on a process you are attempting to monitor is 60.0 units. The process population standard deviation is 1.72. Sample size is given to be 16.a) Determine the 3-sigma x-chart control limits. Upper Control Limit (UCLİ)- 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 control limits. Upper Control Limit (UCLİ- units (round your response to two decimal places) Lower Control Limit LCLİ)- units round your response to two decimal places ). How do the control limits change?
