Quizplus · Accepted Answer

The scatterplot shows that U.S. life expectancy has been increasing over time, so statement A is true. However, the scatterplot does not show a decrease in life expectancy between 2008 and 2010, so statement B is false. Statement C is true based on the increasing trend in the scatterplot. Statement D cannot be determined from the scatterplot alone, so it is not true or false. Therefore, only statement B is not true based on the scatterplot.
