You are conducting a small cohort study on hyperactivity in children, ages 5-7. After screening 300 rural children you find that 25 are already diagnosed with hyperactivity. You follow these children for one year and you interview them every month. You are concerned about one variable, playing video games for more than 30 minutes per day. At the end of one year you find that of those students exposed to more than 30 minutes of playing video games per day, 75 had hyperactivity while 36 children did not. You also find that those students who were not exposed to more than 30 minutes of video games per day hour of playing 15 had hyperactivity while 68 did not. What is the Relative Risk?
