Question

Enough money has been budgeted to collect independent random samples of size n1 = n2 = 100 from populations 1 and 2 in order to estimate (p1 – p2). Prior information indicates that p1 = p2 = .6. Have sufficient funds been allocated to construct a 90% confidence interval for (p1 - p2) of width .1 or less? Justify your answer.
