Require the use of a graphing calculator.
The data given shows the growth of the total U.S. National Debt (in billions) for the years 1993 to 1999 (1993 → 1), and for the years 2001 to 2007 (2001 → 1), for each set of data, enter the data into a graphing calculator, then
a. Set an appropriate window for viewing the scatterplots, and determine if the associations are linear or nonlinear.
b. If linear, find the regression equation for each data set and graph both (as Y1 and Y2) in the same window (round to two decimal places).
c. During which 7-year period did the national debt increase faster? How much faster?
