6. Active is an energy drink that claims to provide physical strength. To test this claim, the
producers of Active conducted a study. The company recruited 25 high school athletes and 4
professional football players to participate in the study. The high school athletes were each
randomly assigned to drink between 1 and 5 ounces of Active. The professional football
players were assigned to drink either 30 or 31 ounces. After waiting 10 minutes they
completed as many pull-ups as they could. Here is a scatterplot showing the number of
energy drinks consumed and the number of pull ups that were completed by each participant,
as well as a line of best fit.
Which of the following would increase if
the professional football players were
removed from the data set?
umber of Pull Ups
(A)r
(B)r^2
(C) the slope
(D) the standard deviation of the residuals
(E) None of the above.
