There is a mistake... -> df1 is not necessary to be greater than df2, sample 1 and sample 2 are taken in the order that is given in the question, only Z must be more than 1 so, for that we change the formula S1^2 / S2^2 or S2^2 / S1^2 according to our need i.e when S1>S2 or S2>S1. other then that I liked the video and great teaching

sir agar v1 10 se jyada hoga tab kya karenge, table me se value kaise nikalenge fir. jaise niche diye gaye question me hai. The standard deviation of a random sample of 1000 is found to be 2.6 and the standard deviation of another random sample of 500 is 2.7 . Assuming the sample to be independent, find whether the two samples could have come from populations with the same standard deviation.
