The scatterplot in Fig.60 describes the ages and years of experience of NFL football players. To enter the NFL, a player must be at least three years removed from completing high school, or the player must have completed at least three years of college.

a. Explain why the red dot is an outlier. Estimate its coordinates. What do they mean in this situation? How can you tell a recording error must have been made? If all the data were part of a study, what should be done about the outlier?
b. Estimate the coordinates of one other point that is probably the result of a recording error. What do they mean in this situation? How can you tell a recording error was probably made?
c. In parts (a) and (b), you have described outliers. Now describe the three other characteristics of the association. You do not have to compute r.
