1) The average weight of Breed A is 9 pounds, and the average weight of Breed B is 12.25 pounds.

2) Factors that could contribute to the different weights seen within breeds include genetics, diet, exercise, and overall health of the rabbits.
3) To track and find the growth rate of the two rabbit breeds during an investigation, you would need to regularly weigh the rabbits at specific intervals and compare the weights over time. By tracking their growth, you can determine how quickly each breed is growing and identify any patterns or differences between them.
