Sample proportions of sample size n = 100 from a population with p = 0.4

Find the mean and standard error of the sample proportions two ways:
(a) Use StatKey or other technology to simulate at least 1000 sample proportions. Give the mean and standard error and comment on whether the distribution appears to be normal.
(b) Use the formulas in the Central Limit Theorem to compute the mean and standard error. Are the results similar to those found in part (a)?
