Consider all samples of size 5 from this population:6 8 10 12 13
1. Compute the mean and variance of the population
2.list all samples of size 4 and compute the mean for each sample
3.construct the sampling distribution of the sample means
4.Calculate the mean of the sampling distribution of the sample means and compare this to the mean of the population
