HW6#16
The assets (in billions of dollars) of the four wealthiest people in a particular country are 29, 26, 13, 11. Assume that samples of size n=2 are randomly selected with replacement from this population of four values.
A. After identifying the 16 possible samples, find the mean of each sample, then construct a table representing the sampling distribution of the sample mean.
B. Compare the mean of the population to the mean of the sampling distribution of the sample mean.
C. Do the sample means target the value of the population mean? In general, do sample means make good estimates of population means? why or why not?

The assets (in billions of dollars) of the four wealthiest
people in a particular country are 43,35, 22,15. 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
