The table shows the weights of puppies and kittens in a pet store. In this activity, you'll find the mean and the mean absolute deviations of this data set. Then you’ll compare these values to determine the degree of overlap for the two data distributions. Kitten Weight

Part A
What is the mean weight in pounds of the kittens in the store?
Part B
What is the mean weight in pounds of the puppies in the store?
Part C
Calculate the absolute deviation (difference) of the mean weight of the kittens and each kitten’s recorded weight. Kitten Weight

Part D
Use the table in part C to find the mean absolute deviation of the kitten weights.
Part E
Calculate the absolute deviation (difference) of the mean weight of the puppies and each puppy’s recorded weight.
