Question:

The National Snow and Ice Data Center at the University of New Hampshire collected data on the temperature of ice core samples from a glacier snow pit. The ice core samples were collected from depths ranging from 2 meters to 175.5 meters. The data for depths up to 20 meters are listed in the next table.

a. Plot the data in a scattergram, with temperature on the y-axis and depth on the x-axis. What trend do you observe? 

b. Propose a polynomial model for E(y) that you think will fit the data. What is the order of the model?

c. Fit the model, part b, to the data using the method of least squares. Assess the adequacy of the model.
