Question

Referring to Problem 13.60, instead of predicting the unit density, you now wish to predict the foam diameter from results stored in PackagingFoam4 . Develop a multiple regression model that uses die temperature and die diameter to predict the foam diameter (mg/ ml). Be sure to perform a thorough residual analysis. Do you think that you need to use both independent variables in the model? Explain.
