We are interested in looking at the effect of a baseball player's free-agent status on their salary. We look at 337 baseball players and categorize them as either having a high salary (above 2 million) or not, and as either being free agents or not.

1. Looking at the stacked bar chart, does there appear to be a difference in the conditional distribution of High Salary dependent on whether or not you are a free agent? How can you tell?

2. If we want to perform a ?2 test to see if there is a relationship between the two variables, what is our null and alternative hypothesis?
