Question: Researchers in Food Science studied how big people's mouths tend to be. They measured mouth volume by pouring water into the mouths of subjects who lay on their backs.

(Mouth volume is measured in cubic centimeters and height in meters.)
The data were checked and deemed suitable for regression. Take a look at the computer output.
