1.Each year, a magazine publishes a list of the richest people in a country. In the last year’s issue, the six richest people and their wealth (to the nearest billion dollars) are as shown in the following table. Consider these six people a population of interest.
Person Wealth ($ billions)
A 66
B 57
C 43
D 38
E 38
F 32
a. Calculate the mean wealth, µ, of the six people. (Round to one decimal place)
b. For samples of size 2, construct a table of all possible samples and their sample means.
c. Find the mean of the sample means.
2.Mobile Homes. According to the U.S Census bureau publication Manufactured Housing Statistics, the mean price of new mobile homes is $65,100. Assume a standard deviation of $7200. Let x denote the mean price of a sample of new mobile Homes.
a. For samples of size 50, find the mean and standard deviation of x
b. Repeat part a with n = 100

According to the Census Bureau publication Current Construction Reports, the mean price of new mobile homes is $38,400. The standard deviation of the prices is $7,200. A sample of size 100 yields sigma(sub x-bar) = $720.00. What sample size is needed in order for sigma(sub x-bar) to equal $360?

The Census Bureau groups data on households into census tracts,
where each census tract has a total population of about 4,000
residents. Census tracts should be divided so that the households
in the census tracts share certain characteristics, such as
economic status. Even though most tracts are around 4,000
residents, there is some variability, which is the focus of this
lab. In practice, census tracts usually have a population between
1,200 and 8,000 people.
