Chi Square Significance Level tables, someone, change, 630, problems

Regarding chi square (for the two problems above), for a significance level of 0.05, the idea is to look under the 0.95 column.


This seems counter-intuitive to what we do for the rest of the tests. Which is, if we know the alpha, we simply look for that significance level in the tables (alpha/2 for the equality based hypotheses).

Can someone throw some light on this change of behavior for chi square? I want to make sure I am understanding properly so that I know when to look under which column.

Thanks as usual!
