Blood Juicy Jack wants to decide if music affects the heart rate of a person. He designs an experiment to test his idea. He enlists 10 people to listen to 3 different genres of music: rap, country, rock and roll. He first tests their resting heart rates. He then tests each of their heart rates while they listen to 60 seconds of the music. He tests each person 3 times.
