# Question: If Y1 n and Y2 n are the respective independent relative frequencies

If Y1/n and Y2/n are the respective independent relative frequencies of success associated with the two binomial distributions b(n, p1) and b(n, p2), compute n such that the approximate probability that the random interval (Y1/n − Y2/n) ± 0.05 covers p1 − p2 is at least 0.80.
