simulate repeated random sampling, from a variety of distributions and a range of sample sizes, to illustrate properties of the distribution of X⎯⎯⎯ X¯ across samples of a fixed size nn, including its mean μμ, its standard deviation σ/n‾√σ/n (where μμ and σσ are the mean and standard deviation of XX), and its approximate normality if nn is large
