a) what is the cumulative frequency for a weight of 27.5 pounds?
(type an integer or a decimal )

Explanation:

Step1: Identify the x - value

We are looking for the cumulative frequency at a weight of 27.5 pounds. So we locate \( x = 27.5 \) on the x - axis (weight axis) of the ogive graph.

Step2: Find the corresponding y - value

From the x - value of 27.5, we move up vertically until we intersect the ogive curve, and then move horizontally to the y - axis (cumulative frequency axis). By looking at the graph, when \( x = 27.5 \), the corresponding cumulative frequency (y - value) is 40.

Answer:

40
