Find the critical values X2 1 a2 and X2 a2 for a 99 confiden

Find the critical values X² 1- a/2 and X² a/2 for a 99% confidence level and a sample size of n = 25

Solution

Note that

a/2 = (1-c)/2 = (1-0.99)/2 = 0.005

1-a/2 = 0.995

At n = 25, df = n - 1 = 24.

Thus, using table/technology,

chi^2(1-a/2) = 45.55851194 [ANSWER]
chi^2(a/2) = 9.886233502 [ANSWER]
