Kindly use excel for simulation.

Carry out a simulation experiment using a statistical computer package or other software to study the sampling distribution of)? when the population distribution is Weibull with a = 2 and ,8 = 5, as in Example 5.19. Consider the four sample sizes n = 5, 10, 20, and 30, and in each case use 500 replications. For which of these sample sizes does the J? sampling distribution appearto be approximately normal
