There are two aspects to this study: a designed experiment and an
observational study.

0.  What is adiposity?

1.  Who were the subjects of the study?

2.  For the experiment, the children participated in a pair of caloric 
compensation trials.  
a.  What are the treatments?  What is the method of treatment assignment?
b.  What is the response measurement?  What is the range of values 
    for this measurement?  Explain the meaning of each of the
    following scores:  -50%, 0%, 50%, and 100%.  
c.  How were the treatments administered to the children?  

3.  What were the conclusions of this experiment?  Explain the average
COMPX scores for boys and girls.  Using the Figure 1 results, describe
in words each of the three graphs, and find summary statistics for
these three graphs from a table in the report.  Explain why the 3-D
effect makes the information relatively hard to gather.

4.  Is caloric compensation, as measured my COMPX, related to
adiposity in children?

5.  In addition to the experimental response, other information was 
collected on the children and their parents.  What was this information? 

6.  The second part of the study tries to predict the response 
measurement from information on the family.  What information is used 
in this prediction.  

7.  What do the investigators conclude from this second aspect of the
study?  Are these conclusions strong enough to support the newspaper
article's title?  Why or why not?
