The relationship is linear because both the diameter and the unit vary constantly, except for Scott.
RESULTS PART 2
Bounty Brawny Viva Scott Basic Thirsty
The relationship of the two lines are not linear because the unit prices are very similar for all brands.
Advice for Shoppers!
Scott is the best value
brand because it has the
lowest unit price of one
cent. Also, it is tied for the
second highest diameter and
area of absorbency.
