SOC Follow up on problem 12.11 by finding the regression coefficients for the relationship between cell phone use and urbanization. Use the Intl-Pop dataset and the Regression command.

● Load the Intl-Pop database.

● From the main menu bar, click Analyze, Regression, and Linear.

● On the “Linear Regression” screen, place CellPhones in the “Dependent” window and Urban in the

“Independent” window.

● Click OK and results will be printed to the Output screen.

● The “Coefficients” box displays the value of a and b under “Unstandardized Coefficients.” Look in the column labeled B. The value in the first row is a and the entry in the second row is b.

a. State the regression equation with the values for a and b.

b. Use the equation to predict cell phone use for nations that are 25% urbanized (X 5 25), 50% urbanized (X 5 50), 75% urbanized (X 5 75), and 99% urbanized (X 5 99). What happens to cell phone use as urbanization increases?
