Homework 6
----------

Do the following problems from the textbook:

7.8, 7.20, 7.22, 7.23, 7.24, 7.28(b), 7.31,
10.18, 8.3, 8.8(a,c), 8.11, 8.29,
9.4, 9.5, 9.8, 9.10(c), 9.11, 9.18, 9.21.

NOTE: Problems 7.8, 7.24, 10.18, 8.8, 8.11, 
9.10(c), 9.11, 9.18, and 9.21 require analysis 
using a computer package such as SAS or R.

NOTE: For 8.29, in the book's notation, 
the capital X refers to the uncentered values, and 
the lowercase x refers to the centered values.  
This problem can be done most easily using R, I think.

The "Job Proficiency", "Brand Preference", and 
"Commercial Properties" data sets are given on the 
course web page.

Please write your answers neatly and clearly!
