Calculate the correlation between the weights and the amps of the 19 saws.
Calculate the average weight of the saws for each of the five amp ratings.
Calculate the correlation between the average weights and the amps. Is the correlation between average weights and amps greater than, less than, or equal to the correlation between individual weights and amps?
