uppose that the proportion of successes in a population is ? and that a very large simple random sample of size ? 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 ? and standard deviation equal to ?(1−?)?⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯√. The sample proportion is approximately normally distributed if the sample is large enough. The sample proportion is binomially distributed with parameters ? and ?. The...
