**MathMate**, Wednesday, August 12, 2009 at 10:56pmThis is a similar question to the previous where you would have to look up the cumulative probability values for a given value of α and degrees of freedom.

For a 2 by three contingency table, the number of degrees of freedom is (2-1)*(3-1)=2.

For α=0.025, cum.probability=0.975, df=2, Χ²=7.38.

You can get the value for α=0.05 in a similar way.
