X= seconds (round your response to three decimal places). b) What is the value of R? =seconds (round your response to three decimal places). c) What are the UCL; and LCL; using 3-sigma? c) What are the UCLE and LCL; using 3-sigma? Upper Control Limit (UCL3) = seconds (round your response to three decimal places). Lower Control Limit (LCL;) = seconds (round your response to three decimal places). d) What are the UCLR and LCLR using 3-sigma? Upper Control Limit (UCLR) = = seconds (round your response to three decimal places). Lower Control Limit (LCLR) = seconds (round your response to three decimal places). e) Is process in control? Yes. No
