You work for a regulatory agency that oversees the certification of the safety of pesticides.  The manufacturer of a pesticide, used on tomatoes, claims that with proper use, the amount of the pesticide that will be in the tomatoes that go to market will be well below required standards.  Your job is to set-up a statistical analysis of the amount of the pesticide measured in tomatoes.  Which of the following approaches represents the best ethical choice, in terms of protecting human health?Group of answer choicesMeasure the pesticide level in a random sample of tomatoes, and set-up a hypothesis test, with the null hypothesis that the pesticide levels do not meet the standard. Assume that the pesticide is not safe, unless there is evidence to prove otherwise.Measure the pesticide level in tomatoes from one crate, and if they are all meeting the standard, certify the pesticide.Measure the pesticide level in a random sample of tomatoes, and set-up a hypothesis test, with the null hypothesis that the pesticide levels meet the standard. Assume that the pesticide is safe, as long as there is not evidence to prove otherwise.
