Modeling Data The table shows the world populations (in billions) for five different years. (Source: U.S. Bureau of the Census, International Data Base) Let represent the year 1994. (a) Use the regression capabilities of a graphing utility to find the least squares regression line for the data. (b) Use the regression capabilities of a graphing utility to find the least squares regression quadratic for the data. (c) Use a graphing utility to plot the data and graph the models. (d) Use both models to forecast the world population for the year 2010. How do the two models differ as you extrapolate into the future?
