Research suggests that spending time with animals can reduce blood pressure. I want to know whether particular animals are better at reducing blood pressure than others. I randomly select 10 participants. Each participants' blood pressure is measured when they enter the lab (Time 1; baseline). Participants' blood pressure is then measured again after they spend a half-hour with a dog. Lastly, participants' blood pressure is measured a third time after they spend a half-hour with a cat.

Suppose a fish market has 200 fish tested, and 29 of them have dangerous levels of mercury.
