The assets​ (in billions of​ dollars) of the four wealthiest people in a particular country are 33, 29, 23, 18. 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.
