A density curve is plotted on an x y coordinate plane. The x-axis ranges from 0 to 7 in increments of 1, whereas the y-axis is not marked. One line segment forms the curve. It extends horizontally from a point where x = 2 to a point where x = 7. Dashed vertical line segments rise from the x-axis at 2 and 7 to meet the curve at each end. All values estimated. What is the height of the density curve? \text{height}=height=start text, h, e, i, g, h, t, end text, equals
