Bill recorded the weight of 8 of his classmate's pets:

1, 3, 3, 1, 1, 6, 4, 5

To calculate the average weight of the pets you have to add all weights and divide it by the sample size:


X_{\text{bar}=}\frac{\Sigma x_i_{}}{n}
X_{\text{bar}}=(1+3+3+1+1+6+4+5)/(8)=(24)/(8)=3

The average weight of the pets is 3 pounds
