A poll conducted in 2012 asked a random sample of 1358 adults in the United States how much confidence they had in banks and other financial institutions. A total of 149 adults said that they had a great deal of confidence. An economist claims that less than 13% of U.S. adults have a great deal of confidence in banks. Can you conclude that the economist's claim is true? Use both α=0.10 and α=0.01 levels of significance and the P-value method with the TI-84 Plus calculator.

b. Compute the value of the test statistic.

c. Using α=0.10, can you conclude that greater than 71% of emails are spam?

d. Using α=0.01, can you conclude that greater than 71% of emails are spam?

e. state conclusion

In the United States, 7.8% of the population has diabetes. The CDC compiles data from an SRS of 1200 people.

a.What would be the mean number of people who have diabetes from such a sample? What would be the standard deviation?

b.Use the Normal approximation to estimate the probability that at least 115 people (out of the 1200) would have diabetes?

Open a new thread on the discussion board. Many product markets in the United States are monopolisticaly competitive due to the use of product differentiation. What is product differentiation? How does product differentiation give a company market power especially over pricing? Give one or two examples of products that sustain higher pricing due to product differentiation. Is this justified?

According to the course text, the United States has employed a worldwide system of taxation for the past 100 years. The Tax Cuts and Jobs Act (TCJA) upended this system. Imagine you are an international tax consultant advising a client on the impact of P.L. 115-97, the law known as the Tax Cuts and Jobs Act, on the taxation of a controlled foreign corporation (CFC).

• Analyze two changes to CFCs and advise your client on the actions necessary to reduce current and future tax liability as a result of these charges.
• Create a scenario reflecting the taxation under the prior tax and current law to support your recommendations.

2.Do you believe that the three countries (Brazil, United States of American and India) under consideration practice policies that promote globalization? For example, what are those countries' policies toward (a) governance, (b) competitive markets, (c) property rights, and (d) corruption?

3.Determine whether your affiliate marketing is a producer of goods or services. What are the major products and/ or services provided by affiliate marketing? Are those outputs sold only domestically or are they also exported?

4.Do these products and services face tariff or non-tariff barriers in the target export markets? What are the tariff rates or non-tariff barriers imposed on these items?

5.Identify regional trading blocs with which affiliate marketing operates as well as the benefits that affiliate marketing gains because it is part of those trading blocs.

6.Would affiliate marketing be better off under a system of multilateral trade liberalization like the WTO, or with bilateral or regional trading blocs?

7.If you were visiting a foreign country to negotiate a transaction on behalf of affiliate marketing, what cultural knowledge would you need to gain before the visit? How and from where would you get the information?

c)The expenditure approach to computing GDP involves summing which of the following?

d)

In the United States, males between the ages of 40 and 49 eat on average 103.1 g of fat every day with a standard deviation of 4.32 g. The amount of fat a person eats is not normally distributed. A random sample of 33 men age 40-59 in the U.S. is taken.

It is possible with rounding for a probability to be 0.0000.

a) Identify the individual, variable, type of variable and the random variable X in the context of this problem. The individual is ________________

The variable information collected from each individual is _________________

This variable is a ___________- variable.

The random variable X is as follows: _____________________

b) List the givens with the correct symbols.

? = 103.1 g

? = 4.32 g

? = 33

c) Identify the random variable ¯¯¯ X in the context of this problem. __________________________

d) Find the mean of the sampling distribution of the sample mean. Put the numeric value in the first box and the correct units in the second box.

e) Find the standard deviation of the sampling distribution of the sample mean. Put the numeric value rounded to two decimal places in the first box and the correct units in the second box.

f) What is the shape of the sampling distribution of the sample mean? _________________

Check all that apply:

σ is unknown

σ is known

n is at least 30

population is not normal

n is less than 30

population is normal

g) Find the probability that the sample mean fat consumption of the 33 randomly selected males in the US age 40 to 49 is less than 104.1 g.

Round final answer to 4 decimal places.

DO NOT use the rounded standard deviation from part e in this computation.

Use the EXACT value of the standard deviation with the square root.

h) Find the probability that the sample mean fat consumption of the 33 randomly selected males in the US age 40 to 49 is less than 101.6 g.

Round final answer to 4 decimal places.

DO NOT use the rounded standard deviation from part e in this computation.

Use the EXACT value of the standard deviation with the square root.

i) Is a mean fat consumption of 101.6 g unusually low for 33 randomly selected males in the US age 40 to 49?___________________________

j) If you found a mean fat consumption for a sample of 33 males in the US age 40 to 49 as low as 101.6 g, what might you conclude? _____________________

2. Consumption spending is a large percentage of GDP in the United States. The ageing population is a demographic certainty. Explain how ageing demographics in the U.S. will affect the economy for each of the two views discussed below.

a. Using key macroeconomic measurements and models explain how ageing demographics traditionally has already affected several economies (such as Japan and Europe.

b. Now explain how ageing demographics will affect U.S. consumers and U.S. consumers and U.S. businesses if older people are behind in saving for their retirement and must continue to work to save more for retirement.
