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 when the weight is 27.5 pounds. So we find the point on the x - axis corresponding to 27.5 pounds.

Step2: Find the y - value (cumulative frequency)

From the ogive graph, we trace up from the x - value of 27.5 pounds to the graph line and then horizontally to the y - axis (cumulative frequency axis). By looking at the grid, we can see that the cumulative frequency at 27.5 pounds is 40.

Answer:

40
