Problem 14E

If $$Y_{1} / n$$ and $$Y_{2} / n$$ are the respective independent relative frequencies of success associated with the two binomial distributions $$b\left(n, p_{1}\right)$$ and $$b\left(n, p_{2}\right)$$, compute $$n$$ such that the approximate probability that the random interval $$\left(Y_{1} / n-Y_{2} / n\right) \pm 0.05$$ covers $$p_{1}-p_{2}$$ is at least $$0.80$$. Hint: Take $$p_{1}^{*}=p_{2}^{*}=1 / 2$$ to provide an upper bound for $$n$$.
