The questions below are from previous McMaster University exams when the course was taught by Dr. John MacGregor and other instructors.  We have covered much of the same material - but a few topics were not covered - so don't expect to be able to answer all questions.

Size experiments were performed to assess the effects of the density (:math:`x_1`) and melt index (:math:`x_2`) of polyethylene chips on the quality (:math:`y`) of an extruded part.  It is hypothesized that, over the ranges considered, the effects are linear.  The data are mean centered and so a model of the form :math:`y = b_1x_1 + b_2x_2 + e`  should hold.  The sums of squares and cross products of the data are given below.
.. math::
  \sum{x_1^2} &= 7.0 \\    \sum{x_2^2} &= 3.0 \\  \sum{x_1x_2} &= 4.0 \\  \sum{x_1y} &= 38.0 \\  \sum{x_2y} &= 30.0 \\
 
and
.. math::
y_1 &= f_1(\beta_1, \beta_2) + e_1 \\ y_2 &= f_2(\beta_1, \beta_2) + e_2
Discuss any analysis or checks that one should do prior to the final estimation stage.
