The weights of several kittens are shown on the plot. What is the difference in pounds between the heaviest and the lightest kitten

The difference in pounds between the heaviest and the lightest kitten can be calculated by subtracting the weight of the lightest kitten from the weight of the heaviest kitten.

Let's assume the weight of the heaviest kitten is 4 pounds and the weight of the lightest kitten is 1 pound.

Difference = Heaviest kitten's weight - Lightest kitten's weight
Difference = 4 pounds - 1 pound
Difference = 3 pounds

Therefore, the difference in pounds between the heaviest and the lightest kitten is 3 pounds.
