A process that produces titanium forgings for automobile turbocharger wheels is to becontrolled by using an x-bar chart. Initially, 100 samples of size 4 are collected, and a 3-sigma control chart is set up to monitor the process: UCL=12, CL=10, LCL=8. If the processaverage suddenly shifted to 11, what is probability that the shift will be detected on thesecond sample following the shift?

The problem is about detecting a shift in the process mean using an x-bar control chart with…
