Explanation / Answer

1) Cumulative frequency of 27.5 pounds is

Draw a vertical line passing from weight = 27.5 (x = 27.5) and check where does it intersect the curve

the answer is: 39

2) Weight for Cumulative frequency of 45 is

Draw a horizontal line passing from cumulative frequency = 45 (y = 45) and check where does it intersect the curve

the answer is: 30.5 pounds

3) Beagles wiegh between 22.5 and 29.5 pounds =

draw 2 vertical lines to get cumulative frequency at 22.5 and 29.5 pounds

at 22.5 pounds = 10

at 29.5 pounds = 44

so between 22.5 and 29.5 pounds lies = 44-10 = 34 beagles

4) beagles weight more 30.5 pounds = cumulative freq of 33.5 pounds - cumulative freq of 30.5 pounds

= 50 - 45 = 5

so 5 beagles is the answer
