1. Report your results in a summary (see sample outline on Blackboard under Start Here).
   1. Introduction:  In your own words, briefly discuss the motivation of this research (why would a study on credit card charges be of interest?).
   2. Graph and Summary statistics:  present a graph that summarizes the data along with a table of summary statistics for each variable in the data set.  An interpretation must accompany any graph, chart, or table that you use.
   3. Methods:  
      1. Develop estimated regression equations, first using attendance as the dependent variable and then using number of wins as the independent variable. Discuss your findings.
      2. Develop an estimated regression equation with attendance as dependent variable and both league and wins as the independent variables.  Discuss your findings.
      3. What is the predicted attendance for an America league AAA team with 72 wins?

4. Discussion:  Interpret the statistical decision you arrived at in terms that would be useful for sport organizations.  This section should also include suggestions for further research and/or discussion of additional variables that may provide more precise results.
