Question: Continuing with the preceding PCB problem. The generators used for the PCB study were
(a) Consider the two experimental runs partially described with the A, B, C, and D levels in the small table below. Give the necessary levels (determined by the generators) for E, F, G, H, and J. (Essentially finish filling in the two rows of the table.)
(b) Name 3 effects aliased with the A main effect in this study.
(c) When the values of y obtained in the study are listed in Yates order for factors A through D and the Yates algorithm is applied, the results (again in Yates order, left to right, top to bottom) are
The two largest (in magnitude) of the "fitted effects" computed by the Yates algorithm are -10.13 and -6.38. Give the simplest possible interpretation of these quantities
(d) Suppose the effects you identified in (c) are judged to be the only ones of importance in this study. What settings of factors A through J should one use to produce a minimum y, and what response do you predict if your recommendations are followed? That is, recommend levels of all factors and give a corresponding value of y.
