The level of a pollutant in the river next to a chemical factory is monitored at regular intervals. Over the course of years, the level of the pollutant was determined by chemical analysis. In recent years, the company has made some changes in the factory where increases in the pollutant level can be observed. The environmental protection organization (EPA) wants convincing evidence that the level of the pollutant has not increased. By creating the relevant null and alternative hypotheses, I. type and II. describe type errors.
