Imagine that you are a researcher at a major environmental science university. You are considered a leading authority on a disease that is caused by a particular environmental problem and you have been studying it for the past 25 years. Because of this, a major pharmaceutical company hires you to help them determine whether a new drug they're developing will cure this disease. Being busy with your own research, you ask a couple of your new graduate students to devise an experiment to test the potential effectiveness of the drug. The students quickly come up with an idea: they suggest that you treat 100 patients with the drug at two different dosages, and then follow the patients for a year to see how many recover. Do you think this is a good experiment? Why or why not?
