Question:

Use the data presented in Problem 7b to fit the models W =cg3 and W = kgl2. Interpret these models. Compute appropriate indicators and determine which model is best. Explain.

Data from problem 7b

In the following data, g represents the girth of a fish. Fit the model W = klg2 to the data using the least-squares criterion.

Length, 1 (in.) Girth, g (in.) Weight, W (oz) 14.5 12.5 9.75 8.375 27 17 17.25 14.5 12.625 17.75 14.125
