Use the following to answer the questions below:

The scatterplot shows the relationship between GPA and the number of Facebook friends for 30 students in a class.

A scatterplot shows the relationship between number of Facebook friends and G P A. The horizontal axis is labeled number of Facebook friends and ranges from 0 to 1600 in increments of 200. The vertical axis is labeled G P A and has markings from 2.50 to 4.00 in increments of 0.25.The dots are randomly scattered throughout the graph. The dots are plotted between the points, 200 to 1500 on the horizontal axis and between the points, 2.10 to 3.95 on the vertical axis. The concentration of the dots is more between the points 300 and 1100 on the horizontal axis and between the points, 2.75 and 3.75 on the vertical axis. Two outliers lie at the points (200, 3.85) and (1500, 2.30). All values are approximate.


The correlation between GPA and the number of Facebook friends is -0.686. Should you go "unfriend" some of your Facebook friends if you want to improve your GPA (i.e., can you conclude that having more Facebook friends lowers GPA)?
