Question: A random variable x has mean px and standard deviation ox, Suppose n Independent obse/ations of x are taken and the average i of these

A random variable x has mean px and standard deviation ox, Suppose n Independent obse/ations of x are taken and the average i of these n observations is computed. If n is very large, the law of large numbers implies that a, the standard deviation of 2 will be close to ox Ob will be approximately normally distributed c. All of the answers are correct. d. 2 will be close to X
