This study investigates the hours per month spent on the Internet by U.S. residents, age 18 to 24. The sample results are: n= 75, x-bar=28.5, and s=23.1 . We are to construct a 95% confidence interval based on this information.

a) What is critical value of t (that is, t*) for this confidence interval?

b) the standard error of the mean (SEM) is:

c) Rounded to one decimal place, as x-bar was, the margin of error (MOE) for your confidence interval will be:

1. Which of the following represents an important difference between the United States and a socialist economy?

1. In the U.S., most forms of capital are available to private ownership; in a socialist system, they are generally not.
2. In a socialist system, the government conducts extensive research activities; in the U.S., it does not.
3. The U.S. is an example of pure capitalism; a socialist system is an example of mixed capitalism.
4. In a socialist system, the government decides how much of each kind of good is to be produced; in the U.S., this is left entirely to business firms.
5. The socialist system relies more heavily on markets to answer the basic economic questions.

2. In mixed capitalism, a market demand curve

1. Slopes upward from left to right.
2. Is unaffected by changes in consumers’ incomes and tastes.
3. Shows the amount buyers would like to purchase at various prices.
4. Measures the rate of growth of per-capita output.
5. Shifts as the price falls.

3. A decrease in demand

1. Causes the equilibrium price to rise.
2. Results from a decrease in supply.
3. Increases the quantity sold in the market.
4. Reflects an increasing consumer preference for the item.
5. Means that the demand curve has shifted to the left

simple hypothesis test please be clear with algorithm

The United States and Japan often engage in intense trade negotiations. U.S. officials claim that Japanese manufacturers price their goods higher in Japan than in the United States, in effect subsidizing the low prices in the United States with extremely high prices in Japan. According to the U.S. argument, Japanese manufactures accomplish this by preventing U.S. good from reaching the market.

An economist decides to test the hypothesis that higher retail prices are being charged for automobiles in Japan than in the United States. She obtains independent samples from 50 retail sales in the United States and 50 sales in Japan over the same time. She found the sample average of the U.S. sales to be 26,596 and the sample average of the Japanese sales to be 27,236. The standard deviations were 1,981 and 1,974 respectively.

Using an alpha of 5%, conduct a hypothesis test.

Please solve clearly displaying the following:

Assume that the United States invests heavily in government and corporate securities of South Korea (hereafter, ‘Korea’). In addition, residents of Korea invest heavily in the United States. Approximately $20 billion worth of investment transactions occur between these two countries each year. The total dollar value of trade transactions per year is about $15 million. This information is expected to also hold in the future. Explain how each of the following conditions will affect the value of Korean currency, won, holding other things equal. a) U.S. inflation has suddenly increased substantially, while Korean inflation remains low. b)U.S. interest rates have increased substantially, while Korean interest rates remain low. Investors of both countries are attracted to high interest rates. c) The U.S. income level increased substantially, while Korean income level has remained unchanged d) The U.S. is expected to impose a small tariff on goods imported from Korea. e) Combine all expected impacts to develop an overall forecast.

1)Prior to the dual banking system, the U.S. banking system included:

A.  National banks that used a national currency B.  A powerful central bank responsible for money and credit in the economy

C.  a state banking system   C.  a state banking system

2)Financial innovation in the banking industry often occurs in response to changes in financial markets, the regulatory environment, or new technology. The following questions consider how banks respond to various conditions in the banking industry.   Money-market mutual funds allowed individuals to avoid Regulation Q because:

A.  The funds acquired short-term money-market securities, allowing the shareholder to earn interest that was not subject to interest rate ceilings.

B.  Checking accounts were not subject to Regulation Q. C.  The funds allowed the bank to transfer funds automatically from checkable deposits to nontransaction accounts that are not subject to reserve requirements. D.  The funds imposed deposit-rate ceilings on shareholders.

3)Financial innovation in the banking industry often occurs in response to changes in financial markets, the regulatory environment, or new technology. The following questions consider how banks respond to various conditions in the banking industry. Banks lost cost advantages in raising liabilities (funds) in the 1970s because:

A.  Securitization of loans made it easier to sell loans. B.  Banks were not permitted to engage in off-balance-sheet activity. C.  Banks were no longer subject to reserve requirements.

D.  High inflation led to the process of disintermediation.

Identify the tax issues associated with the following scenarios concerning transfer prices.

Compania de Minerale is an Argentianian company which has 100% of its stock owned by U.S. Minerals, a domestic company. Compania recently discovered a huge supply of iron ore based on a mine it developed in Argentina. Compania is subject to an Argentinian income tax rate of 10% on its mining profits. Compania is required under Argentinian law to sell 20% of its mining output (the iron ore) to the Argentinian national steel company at $400/per ton. The price was set by the government without reference to market iron ore price. Compania also has a contract to sell 30% of its iron ore output to a private steelmaker in Brazil for $900/ton. The Brazilian purchaser will take ownership of the iron ore at the output of the mine in Argentina. The remining 50% of the output will be sold to its parent company, US Minerals for US Minerals to use in its US steel making operations. The iron ore will be transported via truck to plants in. Texas.

Identify some of considerations that should be taken into account in setting the transfer price with US Minerals.

A study of the career paths of hotel general managers sent questionnaires to an SRS of 210 hotels belonging to major U.S. hotel chains. There were 88 responses. The average time these 88 general managers had spent with their current company was 12.7 years. (Take it as known that the standard deviation of time with the company for all general managers is 3.6 years.)

(a) Find the margin of error for an 85% confidence interval to estimate the mean time a general manager had spent with their current company:  years

(b) Find the margin of error for a 99% confidence interval to estimate the mean time a general manager had spent with their current company:  years

(c) In general, increasing the confidence level  the margin of error (width) of the confidence interval. (Enter: ''DECREASES'', ''DOES NOT CHANGE'' or ''INCREASES'', without the quotes.)
