Search for bivariate data (in a magazine, a newspaper, an almanac, or on the Internet) that can be closely modeled by a linear equation.


a. Draw a scatter diagram of the data.


b. Find the equation of the least-squares line and the linear correlation coefficient for the data.


c. Graph the least-squares line on the scatter diagram in part a.


d. Use the equation of the least-squares line to predict a range value for a specific domain value.
