Fictitious Scenario Suppose you perform a hypothesis test relating to environmental
toxins in a thriving small city in West Virginia. Environmental toxins
are at a safe level if they are rated at a score of 10 or fewer. A score
above 10 indicates an unsafe toxin level - a level at which doctors
believe people will develop health problems, diseases, and early
death.
Most of the residents who live there work in coal mines and
currently this is the only place left to do this type of work in the U. S.
The workers have been doing this for generations and have few
other skills. They are happy; they raise families there and the city
used to be known as one of the best places to live and bring up
children.
