I.  Answer SAWA questions 1 through 7 (in complete sentences).

II.  Suppose you are a statistician working for a company which is studying the 
effect of a drug in treating irregular heartbeats.  The variable of interest 
is change in heart rate for each subject given the drug.  Using the drug for 
testing is expensive, so your manager wants to limit the experiment to 10 
subjects.  You feel it may require many more subjects to obtain reliable 
results.  The manager responds, "You're just going to report one number, the 
average change in heart rate, whether you have 10 subjects or 100 subjects. What
 difference does it make?"  In a brief paragraph, reply to the manager's 
comments.
