Answer:

Part A: The outlier is the 60 lbs dogs, because this dog disrupts the common pattern amongst the others, therefore it is an outlier.

Part B: The mean of all 4 dogs is is 28.5, and the mean of the 3 dogs without an outlier is 13.5. This means the difference is 15, hence 28.5-13.5=15

Step-by-step explanation:
part A, 60 pounds is the outlier, as it is the only one which is a very far number from the others
