Question

For the samples summarized below, test the hypothesis at =.05 that the two variances are
equal.
Variance Number of data values
Sample 1 30 9
Sample 2 10 19
A) Reject the hypothesis because the test value 9.00 is greater than the critical value 2.51.
B) Do not reject the hypothesis because the test value 9.00 is greater than the critical value
3.01.
C) Do not reject the hypothesis because the test value 3.00 is less than the critical value
3.01.
D) Reject the hypothesis because the test value 3.00 is greater than the critical value 2.51.

Explanation / Answer

Fo = (S1/S2)^2 =3 F0.025,8,18 =3.01 Since F0.025,8,18 > Fo we accept the hypothesis So C
