If the random variable q follows a chi squared distribution..?

there is a probabilitiy of..


a..05 of observing a value of q greater then 9.24


b..01 of observing a value of q greater then 9.24


c. 0.01 of observing a value of q greater then 15.09


d.0.05 of observing a value of q greater then 15.09

If the random variable q follows a chi squared distribution..?
The chi-square distribution is different depending on the number of degrees of freedom. Without know the number of degrees of freedom it is impossible to answer this question.





When you know the degrees of freedom you can look up the values in a table or use a software program.





There are some applets on line with calculators to find the probabilities. here is a link to one:
