48.3 percent of state and federal prison inmates are 20 to 34 years old.
Work Step by Step
The horizontal axis (x-axis) represents the ages.
The ages 20 to 34 years old are represented by 3 bars -- the third, fourth, and the fifth bars from the left.
These bars represent 14.5 percent, 17.2 percent, and 16.6 percent, respectively.
Thus, the age range 20 to 34 years old represents:
$=14.5+17.2+16,6
\\=48.3$ percent of state and federal prison inmates
