a) Determine the 3-sigma x-chart control limits. Upper Control Limit (UCL;) = 57.76 units (round your response to two decimal places). Lower Control Limit (LCL;) = 52.24 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).

~h3q1b

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 4. a) Determine the 3-sigma \(\bar{x}\)-chart control limits. Upper Control Limit (UCL\(_{\bar{x}}\)) = **57.76** units (round your response to two decimal places). Lower Control Limit (LCL\(_{\bar{x}}\)) = **52.24** units (round your response to two decimal places). b) Now determine the 2-sigma \(\bar{x}\)-chart control limits. Upper Control Limit (UCL\(_{\bar{x}}\)) = ☐ units (round your response to two decimal places).
