Suppose that a scientist takes experimental data on the radius of a propellant grain as a function of powder temperature x1, extrusion rate x2, and die temperature x3. Fit a linear regression model for predicting grain radius, and determine the effectiveness of each variable in the model. The data are given in Table 12.5.
