Line graph with one minus specificity on the horizontal axis and sensitivity on the vertical axis. Both axes are labeled 0.00, 0.50, and 1.00. A solid line starts at one minus specificity = 0 and sensitivity = 0. It rises vertically to sensitivity = 0.7 then goes up in steps until it reaches sensitivity = 1.0 at one minus specificity = 0.4. It is then horizontal until one minus specificity = 1.0. A diagonal line goes from the point 0.0, 0.0 to 1.0, 1.0, A broken horizontal line goes through about 0.93 and a broken vertical line goes through about 0.09.
