Even though the actual concentration of sodium in the drinking water is within the limit, there is a0.0974 probability that the water department will erroneously advise its customers of an above-limit concentration of sodium. Suppose that the water department wants to reduce its risk of erroneously notifying its customers that the sodium concentration is above the limit. Assuming the water department can’t change the mean or the standard deviation of the sodium concentration in the drinking water, is there anything the department can do to reduce the risk of notifying its customers that the sodium concentration is above the limit when it actually is not? No, there is nothing it can do. It can collect more specimens over the course of the year. It can collect fewer specimens over the course of the year.
