Question
The assets (in billions of dollars) of the four wealthiest people in a particular country are
36, 30, 27, 11.
Assume that samples of size
n equals=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.

Explanation / Answer
Population are 36, 30, 27, 11
We have to draw 2 samples with replacement from this population of four values.
They are
Probability distribution of the sample mean is
