if my X squared = 5.4
and my df = 5
How do I find p on the x table?
I have the answer here of about .3
How do you find this?

If a value is not on your table, and you cannot access any other resource, then you're only chance is interpolation ..... Since it's obviously not linear interpolation (because the t-distribution is highly non-linear), it will require practice and experience.
Obviously if you're only using these tables to see if the p-value you get is significant, limited accuracy probably won't matter.
Certainly, if you have to do this in an exam, your instructor will obviously realise the shortcomings of the table and will cook the quesitons accordingly .....
Since this issue is of potential interest to other members reading the above-mentioned thread, I've posted this pm to that thread. Let me know if you're uncomfortable with this and I'll delete (or perhaps modify) it.
Best wishes for your studies.
