Step by Step Solution

Step 1 of 4

(a)

From the ogive the cumulative frequency for a height of 72 inches can be determined by drawing a vertical line from 72 inches on the x-axis to the curve and drawing a horizontal line parallel to the x-axis from the meeting point, as shown below. The point at which the horizontal line intersects the vertical axis is, 48.

Therefore the cumulative frequency for a height of 72 inches is 48.
