**Computing
Project (pp. 86-88), parts A and B only. **

For the Computing Project from section 2.1 on the pages 91 of the
textbook: I want you to complete parts A and B. Use the data points
in Figure 2.1.7(instead of 2.1.9) for part A and the 1900-1990 data
points in Figure 2.1.4 for part B. To find the best-fit line, you may
either use a numerical method (e.g. least-squares) or draw an
accurate graph on graph paper and estimate the slope and y-intercept.
After finding a logistic model in each case, I want you to compare
the prediction which your model would make for the 2008 U.S.
population with the actual value, which you can get from the U.S.
Census Bureau's website.
(Use the July 1, 2008 population estimate.)
