    NFL quarterbacks earn more (on the average) than running backs, who in turn earn more than linemen. The correlation coefficient r between a player's salary and his position is positive, near zero or negative?

    You gather data on the number of hours of TV news broadcasts watched per week and the grade point average (GPA) of juniors majoring in journalism. You expect that TV news broadcast watching will help explain grades.

    The plot of the data shows that students who watch more TV news broadcasts tend to have higher GPAs. A plausible value for the correlation r between hours of TV and GPA is 0 or 0.4?
