STA 402S98 Assignment 8: Quiz in tutorial March 20

1. In a two-factor design with unequal importance of treatment means, either

• Prove that µ1. = µ2. implies E(Y | A=1) = E(Y | A=2), or
• Prove by a numerical example that the statement is not true in gerneral.

2. Suppose we have a two-factor design with unequal importance of treatment means, and an additive model applies, so that there is no interaction. For this  situation, either

• Prove that µ1. = µ2. implies E(Y | A=1) = E(Y | A=2), or
• Prove by a numerical example that the statement is not true in gerneral.

Now read Chapter 23 and do problems 23.4 and 23.5. Do 23.7 using SAS to do most of the calculations.

Bring both your log file and your list file to the quiz. Do not edit either file except maybe to remove ^L characters. Do not write anything except your name and student number on either printout.
