Consider the density curve below. A density curve is plotted on an x y coordinate plane. The x-axis ranges from 0 to 5 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 = 1 to a point where x = 5. Dashed vertical line segments rise from the x-axis at 1 and 5 to meet the curve at each end. All values estimated. What is the height of the density curve?
