A water treatment plant needs to maintain the ph of the water in the
reservoir at a certain level. To monitor this, they take 2 oz. of water at 37
locations every hour, measure the ph at each of those locations, and find
their average. If the ph level of the reservoir is ok, the results at each
location will have varying results, with an average pH of 8.5 and a standard
deviation of 0.22. If the pH level of the reservoir is ok, what is the probability
that the sample average is LESS than 8.40?
