Normal Approximation to the Binomial

To use a normal approximation to the binomial, which of the following does not have to be true? (a) n p ≥10, n(1-p) ≥10( or: n p ≥5, n(1-p) ≥5). (b) The individual trials must be independent. (c) The sample size in the problem must be too large to permit doing the problem on a calculator. (d) For the binomial, the population size must be at least 10 times as large as the sample size. (e) All of the above are true. | Numerade
