In testing the independence of two variables described in a contingency table, determine the critical value of chisquare if the test is to be conducted at the
a. á= 0.025 level and d f = 5
b. á = 0.05 level and d f = 8
c. á = 0.01 level and d f = 6
d. á = 0.10 level and d f = 4

It is the same distribution table as the other Χ² values.
For example, at α=0.025 and df=5,
look up cumulative probability of 0.975 to get 12.8.
At α=0.1 and df=6, for cumulative probability of 0.90, Χ² = 10.7.
If you do not have a Χ² table, try the calculator below:

but make sure you have access to one for your exams. Check with your teacher.
