Hey pwillia.

I took a look at your table for chi-square and your results are not right: the square term and the (O-E)^2/E should all be positive terms. Try recalculating these terms to get a valid chi-square test statistic.

Also I'd recommend you also look at a regression analysis. If you are looking at testing say a model of Y = AX + B with H0: A = 0 vs H1: A != 0 then this can be done using standardized regression analysis with statistical software like R (which is free) or SAS (which is expensive).

You can also relate the chi-square results to the regression results to confirm that both answers are reasonable.

The regression can be used to add extra terms and you can test each co-efficient individually in a variety of different ways.
