This exercise uses the data from Exercise 8.9. Use the nonlinear model Y = αX^γ
+ ϵ to represent the relationship between Y (on the original scale, Y = dry weight) and volume. Divide volume by 1,000 to make the numbers more manageable. Fit the model, plot the residuals, and summarize the results. Define a reduced model that will test H₀: γ = 1. Is this reduced model nonlinear? Complete the test and state your conclusion.
