To calculate the average weights, we add the weights for each breed and divide by the number of rabbits. For Breed A, the average weight is (10 + 8 + 7 + 10 + 9 + 9 + 10 + 9) / 8 = 9.0 pounds. For Breed B, the average weight is (10 + 12 + 14 + 13 + 10 + 15 + 11 + 12) / 8 = 12.5 pounds.
Factors contributing to the different weights within breeds can include genetics, diet, age, and overall health of the rabbits. Additionally, environmental factors such as living conditions and stress levels might also play a significant role in weight variation.
To track and find the growth rate of the two rabbit breeds during an investigation, I would measure the weights of the rabbits at regular intervals (e.g., weekly or monthly) from a young age until maturity, while also ensuring proper and consistent diet and living conditions are maintained. This data could then be analyzed to determine trends and patterns in weight gain over time, allowing for precise calculation of growth rates for each breed.
