Due:  Wed. Apr. 1 in class.

Remember to turn in your SAS code and any SAS output that is directly
relevant to the question being answered.

1. Textbook problems:   18.15, 18.24

2. Textbook problems (use SAS for calculations; write out answers to all 
   parts of each question):

   18.40 (enter the data yourself),
   18.46 (the “baseline” and “after 20 days” variables are in a dataset 
         called ”tcells.dat” on the course web page; you will need to 
         calculate the difference in your SAS data step.)
