Part C:
Is GPA linked to pencils?
For their final statistics project, Jordynn and Angie surveyed a random sample of 50 students at
their school. Each student in the survey reported his or her GPA and the number of pencils in
his or her possession at the moment. The association between number of pencils and GPA is
linear, with a correlation of r = -0.23.26 Does the negative association suggest that carrying
fewer pencils will increase a student’s GPA? Explain.
