An application of the distribution of sample meansPeople suffering from hypertension, heart disease, or kidney problems may need to limit their intakes of sodium. The public health departments insome US states and Canadian provinces require community water systems to notify their customers if the sodium concentration in the drinkingwater exceeds a designated limit. In Massachusetts, for example, the notification level is 20 mg/L (milligrams per liter).Suppose that over the course of a particular year the mean concentration of sodium in the drinking water of a water system in Massachusetts is18 mg/L, and the standard deviation is 6 mg/L.Imagine that the water department selects a simple random sample of 32 water specimens over the course of this year. Each specimen is sent toa lab for testing, and at the end of the year the water department computes the mean concentration across the 32 specimens. If the meanexceeds 20 mg/L, the water department notifies the public and recommends that people who are on sodium-restricted diets inform theirphysicians of the sodium content in their drinking water.Use the Distributions tool to answer the following question. (Hint: Start by setting the mean and standard deviation parameters on the tool tothe expected mean and standard error for the distribution of sample mean concentrations.)Normal DistributionMean = 19.5Standard Deviation = 0.85OT10.0-11.012.0-9.014.0-7.0-5.016.0-3.0.500018.0-1.0.5000T20.019.500.00001.022.03.024.05.0MZ Even though the actual concentration of sodium in the drinking water is within the limit, there is adepartment will erroneously advise its customers of an above-limit concentration of sodium.probability that the waterSuppose that the water department wants to reduce its risk of erroneously notifying its customers that the sodium concentration is above thelimit. Assuming the water department can't change the mean or the standard deviation of the sodium concentration in the drinking water, is thereanything the department can do to reduce the risk of notifying its customers that the sodium concentration is above the limit when it actually isnot?O It can collect fewer specimens over the course of the year.O No, there is nothing it can do.O It can collect more specimens over the course of the year.
