Atmospheric pressure: The following table gives a measurement of atmospheric pressure, in grams per square centimeter, at the given altitude, in kilometers.
(For comparison, 1 kilometer is about 0.6 mile, and 1 gram per square centimeter is about 2 pounds per square foot.)
a. Plot the natural logarithm of the data, and find the equation of the regression line for the natural logarithm of the data.
b. Make an exponential model for the data on atmospheric pressure using the logarithm as a link.
c. What is the atmospheric pressure at an altitude of 30 kilometers?
