The assests (in bilions of dollars) of the four wealthiest people in a particular country are 39, 33 16, 15. Assume that samples of size n=2 are randomly selcted with replacement frm this popluation of four values.
After indentifying 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.
