A2. Sketch the sampling distributions of ii for 3 different sample sizes: N= 10, N =100 and N=10000 on the same graph. Also add to this graph the sampling distributions of n as the sample size Nm. Make sure you denote on your graph the true population mean u and the value around which the sampling distributions of it is centred for each sample size. Would you use this estimator? Explain.
