A bar chart shows income on the x axis and percentage voting on the y axis. Less than 10,000 dollars, 49. 15,000 to 19,999 dollars, 56. 30,000 to 39,999 dollars, 62. 50,000 to 74,999, 70. 100,000 to 149,999, 79. Look at the bar graph, which shows voter turnout in one election year. Which is the best conclusion someone can draw from this graph? All income groups vote at roughly the same percentage. The less one earns, the less likely one is to vote. Middle-income people vote at higher rates than other Americans. Income has very little to do with voter turnout.
