The temperature at which water boils (the boiling point) depends on elevation: The higher the elevation, the
Question:
a. Let B be the boiling point (in degrees elevation of E thousand meters. Construct a scatterplot by hand.
b. Draw a linear model on your scatterplot.
c. Mount Everest, the highest mountain in the world, reaches 8850 meters at its peak. Predict the boiling point of water at the peak. Did you perform interpolation or extrapolation? Explain.
d. The Armstrong limit is the altitude at which water boils at body temperature (about 98.6°F). So, at that altitude, the saliva in a person€™s mouth would boil. Predict the Armstrong limit. Did you perform interpolation or extrapolation? Explain.
e. Extrapolation is bad practice, unless there is some underlying principle that tells us a model describes the situation well for values outside the scope of the data. The Armstrong limit is reportedly between 18.9 and 19.4 thou- sand meters (Source: NASA). Is the result you found in part (d) between these values?
