A school guidance counselor examines the number of extracurricular activities that students do and their grade point average. The guidance counselor says,

“The evidence indicates that the correlation between the number of extracurricular activities a student participates in and his or her grade point average is close to zero.” A correct interpretation of this statement would be that

(a) active students tend to be students with poor grades, and vice versa.

(b) students with good grades tend to be students who are not involved in many extracurricular activities, and vice versa.

(c) students involved in many extracurricular activities are just as likely to get good grades as bad grades; the same is true for students involved in few extracurricular activities.

(d) there is no linear relationship between number of activities and grade point average for students at this school.

(e) involvement in many extracurricular activities and good grades go hand in hand.
