Homework 5
----------

Do the following problems from the textbook (see notes below!):

6.5(a,b,d), 6.6(a,b), 6.7(a), 6.8, 
6.18(c,e), 6.19(a,c), 6.23(a), 6.25,
3.2, 3.3(c,d), 3.6(b,c), 3.16(a,c,d,e,f).


NOTE: Problems 6.5, 6.6, 6.7, 6.8, 6.18, 6.19,
3.3, 3.3, and 3.16 require analysis using a 
computer package such as SAS or R.

NOTE:  For 6.5(d) and 6.18(e), only do the 
residual plot of the residuals against the predicted 
values, Y-hat (i.e., the type of plot we did an 
example of in class).

NOTE: For 3.3(d) and 3.6(c), do a normal Q-Q plot of 
the residuals and also do the Wilk-Shapiro test for
the normality of the errors.

NOTE:  For 3.16(c), note that the function for base-10
logarithms is log10( ), both in SAS and in R.

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

Please write your answers neatly and clearly!
