A cоnsumer prоtectiоn аgency is testing а sаmple of cans of tomato soup from a company.  If they find evidence that the average level of the chemical bisphenol A (BPA) in tomato soup from this company is greater than 100 ppb (parts per billion), they will recall all the soup and sue the company.    Briefly explain a type II error means in this situation,  using the context of this problem.   I am not asking for the definition of a type II error.  I am asking:  If you had to explain to a person of reasonable college intelligence but who does not know statistical terms, that a type II error had been made, what would you tell them?   What did the results of the test make us believe about the cans of tomato soup and what is the truth about the truth about the population of tomato soup cans from this company?
