(b) For each observation, calculate ln x and ln y. Plot the log-transformed data points on a scat-terplot. What type of relationship appears to exist between ln x and ln y? (c) The scatterplot from part b suggests that the transformed model ln y = 0 + 1 ln x + may be appropriate. Fit the transformed model to the data. Is the model adequate? Test using = .05. (d) Use the transformed model to predict the value of y when x = 30. [Hint: Use the inverse transformation y = eln y.]
