For an $\bar { x }$ control chart,you test a series of sample means.For each series of samples,we want to determine whether there is sufficient evidence to infer that the process mean has changed (i.e.reject H₀: the process is under control).Under what situation would you reject the null hypothesis based on the control chart?
