A process has mean 12 and standard deviation 3. The process is monitored by takingsamples of size 5 at regular intervals. The process is declared to be out of control if a pointplots outside the 30 control limits on an X chart.If the process mean shifts to 14, what is the average number of samples that will bedrawn before the shift is detected on an X chart?b.a.An upward shift to what value will be detected with an ARL of 4?If the sample size remains at 5, to what value must the standard deviation be reduced toC.produce an ARL of 4 when the process mean shifts to 14?d.If the standard deviation remains at 3, what sample size must be used to produce anARL no greater than 4 when the process mean shifts to 14?
