Written using notation, we must verify both of the following: Expected number of successes is at least 10: np ≥ 10. Expected number of failures is at least 10: n (1-p) ≥ 10.The standard deviation of the difference is: σ p ^ 1 − p ^ 2 = p 1 ( 1 − p 1) n 1 + p 2 ( 1 − p 2) n 2. (where n 1 and n 2 are the sizes of each sample). This standard deviation formula is exactly correct as long as we have: Independent observations between the two samples. Independent observations within each sample*.
