There is a population of four people:Amy, Ben, Clara, and Donna[Note:this is a population, not a sample.]They are asked how old they are.Amy is 26 years-old, Ben is 18 years-old, Clara is 18 years-old, and Donna is 30 years-old.We are too lazy to poll the entire population, so we take a sample of two people (with replacement and order matters).Please draw the sampling distribution of the mean of a sample of size two.
