Aprocess is normally distributed and in control, with known mean and variance, and the usual three-sigma limits are used on the control chart, so that the probability of a single point plotting outside the control limits when the process is in control is 0.0027. suppose that this chart is being used in phase i and the averages from a set of m samples or subgroups from this process are plotted on this chart. what is the probability that at least one of the averages will plot outside the control limits when m = 5? discuss the results that you have obtained.
