The assets (in billions of dollars) of the four wealthiest people in a particular country are 37, 25, 23, 16. Assume that samples of size n = 2 are randomly selected with replacement from this population of four values. a. After 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 been combined. X Probability X Probability 37 24 31 23 30 20.5 26.5 19.5 25 16 (Type integers or fractions.)
