Answer

Explanation:

Step1: Locate test - score on x - axis

Locate 50 on the horizontal test - score axis.

Step2: Find corresponding percentile

Draw a vertical line up from 50 on the x - axis until it intersects the ogive curve. Then draw a horizontal line from the intersection point to the vertical percentile axis. The approximate value on the percentile axis is around 20.
