Question
The scatterplot above represents the head lengths, in centimeters (cm), and body lengths, in cm, of 14 adult crocodiles. The line of best fit for the data is also shown. The box plot above summarizes the body lengths of the 14 crocodiles.
Based on the line of best fit, of the following, which is the best estimate of the increase in predicted body length, in cm, for every 10 cm increase in head length?
- 25
- 75
- 125
- 150
The correct answer is: 75
For every 10 cm increase in head length we above an increase of more than 50 and less than 100 of body length. From options, the best possible suitable answer is 75.
