Question
The assets? (in billions of? dollars) of the four wealthiest people in a particular country are 36, 32, 27 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 combined.

Explanation / Answer
x probability
36 P(36,36) = 1/4 * 1/4 = 1/16
34 P(36,32) + P(32,36) = 2 * 1/4 * 1/4 = 1/8
32 P(32,32) = 1/4 * 1/4 = 1/16
31.5 P(36,27) + P(27,36) = 2 * 1/4 * 1/4 = 1/8
29.5 P(32,27) + P(27,32) = 2 * 1/4 * 1/4 = 1/8
27 P(27,27) = 1/4 * 1/4 = 1/16
25.5 P(36,15) + P(15,36) = 2 * 1/4 * 1/4 = 1/8
23.5 P(32,15) + P(15,32) = 2 * 1/4 * 1/4 = 1/8
21 P(27,15) + P(15,27) = 2 * 1/4 * 1/4 = 1/8
15 P(15,15) = 1/4 * 1/4 = 1/16
