Question
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 limits.
Upper Control Limit (UCL) = 56.38 units (round your response to two decimal places).
Lower Control Limit (LCL) = 53.62 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 places).
