1) To calculate the average weights of the two rabbit breed groups, we add up the weights for each breed and then divide by the total number of weights.
For Breed A: (10 + 8 + 7 + 10 + 9 + 9 + 10 + 9) / 8 = 8.875 pounds
For Breed B: (10 + 12 + 14 + 13 + 10 + 15 + 11 + 12) / 8 = 11.75 pounds
2) Some factors that could contribute to the different weights seen within breeds include genetics, diet, exercise, and overall health. Genetics play a major role in determining a rabbit's size and weight, as different breeds have different natural sizes. Diet and exercise can also significantly impact a rabbit's weight, as a balanced diet and regular physical activity are important for maintaining a healthy weight.
3) To track and find the growth rate of the two rabbit breeds during an investigation, you could continuously weigh the rabbits at regular intervals, such as weekly or monthly, and plot their weights on a graph over time. By tracking their weight changes over a period of time, you could calculate their growth rate by determining the average weight gain per unit of time. This data can provide valuable insights into the development and health of the rabbits within each breed.
