The assets (in billions of dollars) of the four wealthiest people in a particular country are 39, 33, 29, 13. Assume that samples csize 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 thesampling distribution of the sample mean. In the table, values of the sample mean that are the same have been combined.ProbabilityProbability39293626342333213113(Type integers or fractions.)
