After years of rapid growth, illegal immigration into the United States has declined, perhaps owing to the recession and increased border enforcement by the United States (Los Angeles Times, September 1, 2010). While its share has declined, California still accounts for 23% of the nation’s estimated 11.1 million undocumented immigrants. [You may find it useful to reference the z table.]
a. In a sample of 50 illegal immigrants, what is the probability that more than 20% live in California? (Round “z” value to 2 decimal places, and final answer to 4 decimal places.)
b. In a sample of 200 illegal immigrants, what is the probability that more than 20% live in California? (Round “z” value to 2 decimal places, and final answer to 4 decimal places.)
c. Comment on the reason for the difference between the computed probabilities in parts a and b.
-
As the sample number increases, the probability of more than 20% also increases, due to the lower z value and decreased standard error.
-
As the sample number increases, the probability of more than 20% also increases, due to the lower z value and increased standard error.

After years of rapid growth, illegal immigration into the United
States has declined, perhaps owing to the recession and increased
border enforcement by the United States (Los Angeles
Times, September 1, 2010). While its share has declined,
California still accounts for 29% of the nation’s estimated 11.9
million undocumented immigrants. Use Table 1.

After years of rapid growth, illegal immigration into the United
States has declined, perhaps owing to the recession and increased
border enforcement by the United States (Los Angeles
Times, September 1, 2010). While its share has declined,
California still accounts for 35% of the nation’s estimated 11.3
million undocumented immigrants.

After years of rapid growth, illegal immigration into the United
States has declined because of the recent recession and better
economic conditions in the countries south of the border. But
California still accounts roughly 20% of the nation undocumented
immigrants. If you take a random sample of 50 undocumented
immigrants, what is the probability that more than a quarter (25%)
of them live in California? (HINT: Large sample proportion – use
Normal approximation.) Define p = proportion of all

In the United States, participation in unions has steadily
declined in the private sector but in the public sector, it has
increased. In this unit's discussion boards, comment on the reasons
for this.
Is there no longer a need for union representation in
companies? Is the decline simply because the needs of the worker
have changed? Have basic needs been met and therefore, the things
that the union offers are no longer burning issues for many (most)
employees in the...

Skill-biased Immigration.
(a) Let us consider the immigration dynamics between the United
States and Mexico. The minimum wage of the U.S. is $7.25, while
that of Mexico is $5.1 in U.S. dollars. Let the return to skills in
Mexico be two times of that of the U.S., partly because the U.S.
(Mexico) is relatively abundant (scarce) in the availability of
skilled workers. In other words, if we plot skills x on the
horizontal axis and hourly wage y on the...

Joy’s Frozen Yogurt shops have enjoyed rapid growth in
northeastern states in recent years. From the analysis of Joy’s
various outlets, it was found that the demand curve follows this
pattern:
Q = 200 - 300P + 120I +65T - 250Ac + 400Aj
where Q = number of cups served per week
P = average price paid for each cup
I = per capita income in the given market (thousands of
dollars)
T = average outdoor temperature
Ac = competition’s...
