A side-by-side bar graph has a horizontal axis labeled with 6 count groupings and a vertical axis from 0 to 0.6 with increments of 0.1. There are two vertical bars above each horizontal axis label. For each horizontal axis label, the first bar corresponds to Adults and the second bar corresponds to Teens. The vertical bars in each set have approximate heights as follows, where for each set of 2 bars the horizontal axis label is listed first and individual bar heights are listed from left to right: "None," 0.086, 0.024; "1 to 10," 0.509, 0.218; "11 to 20," 0.130, 0.119; "21 to 50," 0.130, 0.167; "51 to 100," 0.066, 0.185; "100 plus," 0.079, 0.286.

relative frequency distribution for adults:

$R e l a t i v e F r e q u e n c y = \frac{C o r r e s p o n d i n g f r e q u e n c y}{T o t a l F r e q u e n c y}$
