For a one-sample test for a population proportion pp and sample size nn, why is it necessary that np0np0 and n(1−p0)n(1−p0) are both at least 10 ? A)The sample size must be large enough to support an assumption that the distribution of the population is approximately normal. B)The sample size must be large enough to support an assumption that the distribution of the sample is approximately normal. C)The sample size must be large enough to support an assumption that the sampling distribution of the sample proportion is approximately normal. D)The sample size must be large enough to support an assumption that the observations are independent. E)The sample size must be large enough to support an assumption that the sample proportion is an unbiased estimator of the population proportion.
