In a sample of 8 observation, the sum of squared

deviation of item from the mean was 94.5. In

another sample of 10 observation the value was

found to be 101.7. Test whether the difference is

significant at 5% level. You are given that at 5%

level, critical value of F for v1 = 3, V2 = 9 d.f is 3.29

and for V1 = 8, V2 = 10 c.f is 3.07.
