During the 1980s, most of the world's supply of lysine was produced by a Japanese company named Ajinomoto. Lysine is an essential amino acid that is an important livestock feed component. At this time, the United States imported most of the world's supply of lysine—more than 30,000 tons—to use in livestock feed at a price of $1.65 per pound. The worldwide market for lysine, however, fundamentally changed in 1991 when U.S.-based Archer Daniels Midland (ADM) began producing lysine—a move that doubled worldwide production capacity. Experts conjectured that Ajinomoto and ADM had similar cost structures and that the marginal cost of producing and distributing lysine was approximately $0.70 per pound. Despite ADM's entry into the lysine market, suppose demand remained constant at Q = 208 − 80P (in millions of pounds). Shortly after ADM began producing lysine, the worldwide price dropped to $0.70. By 1993, however, the price of lysine shot back up to $1.65. Use Oligopoly to provide a potential explanation for what happened in the lysine market. Support your answer with appropriate calculations.

The stock market and the bond market. Over the period 1928-2013, investments in an index of the Standard and Poor’s 500 stocks have given annual returns of 9.55%, investments in 10-year Treasury Bonds have given a return of 4.93%, and investments in 3-month Treasury bills have yielded 3.55%.
a. (1 point) Which is the most risky of these investments? Describe the risks associated with each investment. Do you think that risk explains the different rates of return?
b. (1 point) Explain which is the most liquid of these investments? Do you think this explains the different rates of return?
c. (1 point) You can buy common stocks only from one of 1366 brokers with a seat on the New York Stock Exchange; treasury bills and bonds are purchased through a broker or directly from the United States government. Do you think these differences might explain the different rates of return?
d. (1 point) How might these different rates of return encourage or discourage the efficient allocation of liquidity and investment resources?

In the following problem:
1. Determine the value of the margin of error ( E ) 2. Construct
the confidence interval. 3. Write a statement that correctly
interprets the confidence interval.
From a Prince Market Research poll in which randomly chosen people
were asked if they felt that U.S. nuclear weapons made them feel
safer the following data was gathered. Construct a 95% confidence
interval for the proportion of all people living in the United
States who felt nuclear weapons made them feel safer.
n = 1800 x = 1543 who said “yes”.
2. A Consumer Reports Research Center randomly surveyed 1000
women to determine what proportion of women purchase books online.
Out of 1000 women, 788 reported that they purchase books
online.
a. Construct a 90% confidence interval for the true proportion of
all women that purchase books online. Write a sentence that
correctly interprets the confidence interval.
b. Can we safely conclude that at least 25% of all women purchase
books online? Why or why not?

Social networking is becoming more and more popular around the world. Pew Research Center used a survey of adults in several countries to determine the percentage of adults who use social networking sites (USA Today, February 8, 2012). Assume that the results for surveys in Great Britain, Israel, Russia, and United States are as follows
| use social network? | UK | Israel | Russia | USA |
| Yes | 344 | 265 | 301 | 500 |
| No | 456 | 235 | 399 | 500 |
a. State the null and alternative hypotheses and conduct a test to determine whether the proportion of adults using social networking sites is equal for all four countries. What is the degrees of freedom? What is the p‐value? Using a 5% level of significance, what is your conclusion?
b. What are the sample proportions for each of the four countries? Which country has the largest proportion of adults using social networking sites? Using a 5% level of significance, conduct multiple comparison tests among the four countries. What is your conclusion? What is the degrees of freedom?

Hello! I do not want you to write an essay for me by any means. I am just completely lost, without inspiration or direction. I am hoping for a few ideas to build from. It's for a composition class, so facts and figures are not important. You'll find the prompt below. Thank you!
A person’s view of America is substantially influenced by how one got here—by choice or by force—and how well one has integrated into the dominant culture. Immigrants choosing to come to the United States have historically integrated faster and fared better than those forced to become Americans.
–Keith Phillips Out of Ashes
Write a well-organized and well-developed essay in which you do the following:
● Describe with examples the differences between two specific ethnic groups with regard to their historical experience in America. Indicate the positive and negative experiences of that population’s integration into American society.
● Indicate the degree to which you feel an individual’s successful contribution to America and enjoyment of American opportunities depends on that person’s race and ethnic experience.
