# Question: Repeat parts b e of Exercise 7 17 for samples of size

Repeat parts (b)–(e) of Exercise 7.17 for samples of size 3. (There are 20 possible samples.)

b. For samples of size 2, construct a table similar to Table 7.2. (There are 15 possible samples of size 2.)

c. Draw a dotplot for the sampling distribution of the sample mean for samples of size 2.

d. For a random sample of size 2, what is the chance that the sample mean will equal the population mean?

e. For a random sample of size 2, determine the probability that the mean wealth of the two people obtained will be within 2 (i.e., $2 billion) of the population mean. Interpret your result in terms of percentages.
