Chapter 3.4, Problem 16E
Remainder Round all answers to two decimal places unless otherwise indicated.
Gross Domestic Product U.S. gross domestic product, in trillions of dollars, is given in the table below.
| Date | Gross domestic product |
| 2010 | 15.0 |
| 2011 | 15.5 |
| 2012 | 16.2 |
| 2013 | 16.7 |
a. Find the equation of the regression line, and explain the meaning of its slope. (Round regression line parameters to two decimal places.)
b. Plot the data points and the regression line.
c. When would you predict that a gross domestic product of 17.3 trillion dollars would be reached? The actual gross domestic product in 2014 was 17.3 trillion dollars. What does that say about your prediction?
