A recent National Science Foundation (NSF) survey indicates that more than 20% of the staff in American research and development laboratories is foreign. Results of the study have been used for pushing legislation aimed at controlling the number of foreign workers in the United States. An organization of foreign-born scientists wants to prove that the NSF survey results do not reflect the true percentage of foreign workers in the U.S. labs. The organization collects a sample of 5,000 laboratory workers in all major labs in the country and finds that 876 are foreign.
a). At 5% level of significance, is there sufficient evidence to conclude that the NSF study overestimated the percentage of foreigners in American laboratories? Your conclusion must be in terms of the P-Value as well as setting up a Rejection Region. Show work.
b). Which statistical distribution should be applied in this situation and why? Explain carefully.
c). What type of error is possible and describe this error in terms of the problem.
d). Based on a 95% confidence level, what is the best case and worst case scenario regarding the percentage of foreigners in American laboratories?
e). Carefully interpret this interval estimation.
f). Using the results of part (d), explain carefully whether or not there is sufficient evidence to conclude that the NSF study overestimated the percentage of foreigners in American laboratories? Explain carefully.

In this assignment, you are asked to begin to pull together the marketing concepts we have been discussing and to think ahead. Entrepeneurship is really a concept of evolution, an idea that often begins as a small business. Before it became Walmart was we know it, Sam Walton's store began in a small town in Arkansas. A similar history exists for McDonald's -- a small hamburger stand in California. In the auto industry, the Dodge Brothers really did exist.
Look around you. Perhaps you know someone who owns or manages a small business. Think about how they bring products (or services) to the marketplace. What are the risks?
Small business is a critical aspect of distribution in the United States. If you were given $150,000 to start a small business, what would it be? What would you do first?
Some of you may be fans of The Shark Tank (on ABC, some cable channels, and Hulu). What are the questions the sharks ask before investing? Other program with a similar concept but different theme are on CNBC. Think about why those questions are important.
Tell me about your small business idea and what you would do to get if off the ground? Be sure to explain your business concept and what you would use the investor's money to accomplish.

One of the most frequently estimated equations in the macroeconomics growth literature are so-called convergence regressions. To investigate this matter, you collect data from 104 countries for the sample period 1960-1990 and estimate the following relationship:
g6090 = 0.020 – 0.360 × gpop + 0.004 × Educ – 0.053×RelProd60
where g6090 is the growth rate (in percentage) of GDP per worker for the 1960-1990 sample period, RelProd60 is the initial starting level of GDP per worker relative to the United States in 1960, gpop is the average population growth rate of the country, and Educ is educational attainment in years for 1985.
(a) What is the effect of an increase of 5 years in educational attainment? What would happen if a country could implement policies to cut population growth by one percent?
(b) It has been suggested to you to interact education with the initial condition to test for additional effects of education on growth. To test for this possibility, you estimate the following regression:
g6090 = 0.015 -0.323 × gpop + 0.005 × Educ –0.051×RelProd60 –0.0028 × (Educ.RelProd60)
Write down the effect of an additional year of education on growth. West Germany has a value for RelProd60 of 0.57, while Brazil's value is 0.23. What is the predicted growth rate effect of adding one year of education in both countries?

Ann is interviewing for job at GRG, Inc.. Bob is the company's hiring manager and is in charge of conducting interviews.
Ann informs Bob that she is in the United States for the next year with an appropriate visa. The job that she is seeking has been advertised as a short-term position to fill a vacancy pending the return of a permanent employee. Without question, Ann is qualified for the position and will remain in the country for a time after the permanent employee returns.
Bob inquires about Ann's national origin after she informed him about the visa. Specifically, Bob asked Ann what country she is from and how many languages she speaks. Bob also made a casual remark about her country's history of "civil unrest" and "history of abusive treatment to women". Bob further informed Ann, during the interview, that he likes to keep up with "foreign affairs" and "contemporary world events". Ann was not offended by Bob's comments or inquiries at the interview.
Ann was not hired for the position. She learned that GRG, Inc. hired a Caucasian female, approximately the same age as she who was born and raised in Illinois. Ann has filed charges of discrimination based on ancestry / national origin with the EEOC. What are her arguments? What are the applicable defenses that GRG, Inc. can raise? Who wins / why not?

Whether this order is profitable or not, would it make sense to accept the order in order to expand into an international market in this scenario?
Scenario:
THE RESILIENTARMOUR Corporation is an American company that manufactures cost-effective protective covers for automobiles made out of innovative composite material, which currently are being sold only in the United States. ResilientArmour currently produces and sells 100,000 protective covers a month and operates its one factory at 60 percent capacity. At that output, the average total cost (ATC) of manufacturing a protective cover is $19.00. Experience has shown that the ATC decreases as output is expanded beyond 100,000 units per month but rises again if output is increased above 125,000 units per month.
THE RESILIENTARMOUR Corporation normally sells its protective covers domestically for $24.00 each. It recently received an order for an additional 10,000 protective covers per month from a buyer in a foreign country where THE RESILIENTARMOUR Corporation would like to do business. This buyer specified that it would pay no more than $14.00 per protective cover. The firm’s accountants estimate that at 110,000 units a month, the ATC of producing a protective cover would be $18.00. THE RESILIENTARMOUR executives want to accept the order.
question: Whether this order is profitable or not, would it make sense to accept the order in order to expand into an international market?
