Does a strong linear correlation exist between altitude and temperature? How do you know?
If a strong linear correlation exists, answer the following:
a.) Find a regression model (ax+b) for temperature as a function of altitude.
b.) If the altitude is 18,500 feet, what would be the expected temperature?
c.) If the temperature is at the freezing mark, what would be the expected altitude?
