ssets (in billions of dollars) of the four wealthiest people in a particular country are 38, 28, 20, 19. Assume that samples of size n = 2 are randomly selected with replacement from this population of four values. ned. r identifying the 16 different possible samples and finding the mean of each sample, construct a table representing the sampling distribution of the sample mean. In the table, values of the sample mean that are the same have b X Probability X Probability 38 24 33 23.5 29 20 28.5 19.5 28 19 integers or fractions.)
