In a sample of 8 observations, the sum of 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 =7 and v, = 9 degrees of freedom is 3.29 and for v, = 8 and v, = 10 degrees of freedom, its value is 3.07.

Question
Transcribed Image Text:In a sample of 8 observations, the sum of 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, = 7 and v, = 9 degrees of freedom is 3.29 and
for v, = 8 and v, = 10 degrees of freedom, its value is 3.07.
