Extracted text: In a sample of 8 observations, the sum of squared deviations of items from the mean was 84-4. In another sample of 10 observations, the value was found to be 102-6. Test whether the difference is significant at 5% level. You are given that at 5% level, critical value of F for v = 7 and v2 = 9 degrees of freedom is 3-29 and for V1 = 8 and v2 = 10 degrees of freedom, its value is 3.07.
