Question:
a. Develop a scatter diagram of the data using the printing speed as the independent variable.
Does a simple linear regression model appear to be appropriate?
b. Develop an estimated multiple regression equation with x = speed and x2 as the two independent variables.
c. Consider the nonlinear model shown by equation (16.7). Use logarithms to transform this nonlinear model into an equivalent linear model, and develop the corresponding estimated regression equation. Does the estimated regression equation provide a better fit than the estimated regression equation developed in part (b)?
