4. Henry Prince has served as a consultant to the Department of Education for several years. Recently he was asked to make a study of high school students to obtain information about how television viewing habits are related to academic performance. Possibly because Henry is always paid by the hour, he has decided to perform two studies. In the first he collected data from 50 randomly selected students on two variables: hours of television watched per week and grade- point average during a given period. In the second study he collected data from 100 students on two variables: number of hours per week working at a paying job and grade-point average during a given period.
