Suppose that the proportion of successes in a population is p and that a very large simple random sample of size n is obtained from that population. What does the central limit theorem say about the distribution of the sample proportion? The sample proportion has mean equal to the population mean y and standard deviation equal to - O The sample proportion is binomially distributed with parameters n and p. The sample proportion is approximately normally distributed if the sample is large enough. p(1-P) The sample proportion has mean equal to p and standard deviation equal to v.
