Question 1202979
with the f-test, the sample with the higher value of variance is the numerator and the other is the denominator.
you have:


n1 = 8
dof1 = 7
m1 = 44
sd1 = 9
v1 = 9^2


n2 = 9
dof2 = 8
m2 = 44
sd2 = 24
v2 = 24^2


sample 2 has the greatest variatiion, so it's the numerator.
the test f-value is 24^2 / 9^2 = 7.11.
the critical f-value is 8/7 = 5.32733457 at .02 level of significance.


the test f-value is greater than the critical f-value so the conclusion is that the variances are not equal.


here's a refeence.
