R=4.40 mm (round your response to two decimal places). c) What are the UCL and LCL, using 3-sigma? Upper Control Limit (UCL.) = 156.12 mm (round your response to two decimal places). Lower Control Limit (LC) - 153,40% mm (round your response to two decimal places). d) What are the UCLR and LCLUsing 3-sigmo? Upper Control Limit (UCLA)* 7.62 mm (round your response to two decimal places). Lower Control Limit (LCA) - 0.08 mm (round your response to two decimal places) c) If the true diameter mean should be 155 mm and you want this as your contor (nominal) line, what are the new UCL, and LCL ?
