Question 454119: . In 2005, John G. Roberts was nominated by President Bush and confirmed by the Senate to be the 17th U.S. Supreme Court Chief Justice. During the nomination process, John G. Roberts's career as a lawyer and judge was the subject of many studies. For example, Kenneth Manning, associate professor of political science at the University of Massachusetts-Dartmouth presented a research paper titled �How Right Is He?� at the 2005 meeting of the American Political Science Association. In cases where Judge Roberts participated, the study categorized the cases into three types: criminal justice, civil rights, and economic activity. In each case, the study also labeled Judge Roberts's vote as either liberal or conservative. Forty-five cases that could not be clearly categorized for the study were not included. At the 0.01 significance level can we conclude Judge Roberts is more conservative in some types of cases?
Criminal Justice Civil Rights Economic Activity
Liberal 6 2 39
Conservative 38 11 49

Ha: they are dependent

I ran a Chi-Sq on the 2 by 3 matrix of data and got the following:
Chi-Sq = 14.496...
p-value = 0.0007119
=====
Since the p-value is less than 1%, reject Ho.
Roberts opinion position tends to depend on the
type of case.
