Reconsider the previous two exercises. Answer the following based on the scatterplot presented above. Do not bother to perform any calculations.
a. Which cat has the largest predicted value for its takeoff velocity?
b. Which cat has the smallest predicted value for its takeoff velocity?
c. Which cat has the largest residual value?
d. Which cat has the smallest residual value?

Data from previous exercises

Harris and Steudel (2002) studied factors that might be associated with the jumping performance of domestic cats. They studied 18 cats, using takeoff velocity (in centimeters per second) as the response variable. They used body mass (in grams), hind limb length (in centimeters), muscle mass (in grams), and percent body fat in addition to sex as potential explanatory variables. Th e data can be found in the CatJumping data file. A scatterplot of takeoff velocity vs. body mass is shown in the figure for Exercise 10.3.15.
