Question

a college professor wonders about the relationship between a students age and how many college credits the student has earned. she surveys one of her classes and calculates that the correlation coefficient is ( r = 0.8 ).
complete the sentences.
in general, older students have earned college credits. the association is a one.
weak
strong

Explanation:

The correlation coefficient \(r = 0.8\) is positive, so as one variable (age) increases, the other (college credits) also tends to increase. Values of \(r\) close to \(1\) (here \(r=0.8\)) indicate a strong linear relationship.

Answer:

In general, older students have earned more college credits. The association is a strong one.
