Assume a population of any 4 numbers(suppose: 4,8,15,19). Select a random sample of size 2 with replacement from the population. List all the possible samples and their corresponding values of x̄ “x-bar” and then find the probability distribution of “X-bar”

study the following:

The distribution of X and the sampling distribution of X-bar
