Carry out a simulation experiment using a statistical computer package or other software to study the sampling distribution of x when the population distribution is lognormal with e[ln(x)] ¼ 3 and v[ln(x)] ¼ 1. consider the four sample sizes n ¼ 10, 20, 30, and 50, and in each case use 500 replications. for which of these sample sizes does the x sampling distribution appear to be approximately normal?
