In a sample of 8 observations, the sum of the squared deviations of items from the mean was 94.5. In another sample of 10 observations 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 v = 3 and v = 9 is 3.29 and for v = 8 and v2 = 10, its value is 3.07.)
