Geothermal power is an important source of energy. Since the amount of energy
contained in 1 pound of water is a function of its temperature, you might wonder
whether water obtained from deeper wells contains more energy per pound.

A. Following steps A-E in the previous question, do a full regression analysis,
using hole depth as the explanatory variable.
B. Using the regression equation, predict the temperature of the water in a well
with an average drill hole depth of 2000m. Is this a reliable prediction?
