Rabbits are very popular domesticated animals, so popular that there are over 300 breeds of domesticated rabbits in the world. You attend a rabbit show and notice that all of the breeds vary in many characteristics, such as size, color, and fur length. You notice that there is weight information on the cages of all rabbit individuals at the show and decide to jot down data for two specific rabbit breeds (in pounds): Breed A: 10, 8, 7, 10, 9, 9, 10, 9 Breed B: 10, 12, 14, 13, 10, 15, 11, 12 calculate both average weights

1 answer

To calculate the average weight for each breed, you add up the weights of all the rabbits in that breed and then divide by the number of rabbits.

For Breed A:

Weights: 10, 8, 7, 10, 9, 9, 10, 9

  1. Sum of weights: \( 10 + 8 + 7 + 10 + 9 + 9 + 10 + 9 = 72 \)

  2. Number of rabbits: 8

  3. Average weight: \[ \text{Average} = \frac{\text{Sum of weights}}{\text{Number of rabbits}} = \frac{72}{8} = 9 \text{ pounds} \]

For Breed B:

Weights: 10, 12, 14, 13, 10, 15, 11, 12

  1. Sum of weights: \( 10 + 12 + 14 + 13 + 10 + 15 + 11 + 12 = 97 \)

  2. Number of rabbits: 8

  3. Average weight: \[ \text{Average} = \frac{\text{Sum of weights}}{\text{Number of rabbits}} = \frac{97}{8} = 12.125 \text{ pounds} \]

Summary:

  • The average weight of Breed A is 9 pounds.
  • The average weight of Breed B is 12.125 pounds.
