in order to keep track of the local alligator population, individual alligators are often tagged. this enables researchers to collect data on each animal continuously. the current weights and lengths of 13 alligators are given in the table. Weights: 51,44,80,28,70,110,83,61,54,106,90,33,95. lengths: 74,61,86,58,88,94,86,72,74,90,86,63,95.

a. based on the patterns in the data, at first glance, which model appears to represent this data best? why?

b. which model is actually the best fit for the data? how do you know?
