DETERMINATION OF COPPER IN DRINKING WATER BY

The mean copper concentration of 190.0 ± 0.6 ppb is way below the Action Level for copper established by the EPA. The result was not surprising due to the copper piping in the building from which the sample was taken. We were not expecting the level to be way over the limit either because there is no known sources of contamination from copper.

Sequential analysis - Wikipedia

History. The method of sequential analysis is first attributed to Abraham Wald with Jacob Wolfowitz, W. Allen Wallis, and Milton Friedman while at Columbia University's Statistical Research Group as a tool for more efficient industrial quality control during World War II.Its value to the war effort was immediately recognised, and led to its receiving a "restricted" classification.
