In 2016, the US Department of Agriculture established a “maximum
acceptable” salmonella
prevalence of 15.4 percent for chicken parts sampled at the end of
a slaughterhouse’s kill line. 54 of the
154 largest chicken-slaughter facilities in the US failed to meet
this standard in 2018. Assume that these
results are representative for all large chicken-slaughter
facilities. Suppose that in a random sample of 60
chicken parts from the large ACME chicken-slaughter facility (which
produces 1,000,000 chicken parts
per year), 45 chicken parts test negative for salmonella.
a) Report a point estimate for the prevalence of failing to meet
the chicken part salmonella standard
among large chicken-slaughter facilities, and test the null
hypothesis that this prevalence is 20%.

The Federal Reserve on Tuesday, March 3, 2020 took the emergency step of cutting the benchmark U.S. interest rate by half a percentage point, an attempt to limit the economic and financial fallout from the coronavirus. Consider the FX market and the money market diagrams we learned within asset approach to exchange rate determination and answer the following questions. Let US be the home country and Euro Area be the foreign country. a) Following the Fed’s decision, explain which schedule(s) shift in the US money market and why. b) Following the Fed’s decision, explain which schedule(s) shift in the FX market and why. c) What happens to the equilibrium E$/€ exchange rate? Why?

An article stated, "Surveys tell us that more than half of America's college graduates are avid readers of mystery novels." Let p denote the actual proportion of college graduates who are avid readers of mystery novels. Consider a sample proportion p̂ that is based on a random sample of 210 college graduates.
(a) If p = 0.6, what are the mean value and standard deviation of p̂? (Round your answers to four decimal places.)
If p = 0.7, what are the mean value and standard deviation of p̂? (Round your answers to four decimal places.)
(b) Calculate P(p̂ ≥ 0.7) for p = 0.6. (Round your answer to four decimal places.)
Calculate P(p̂ ≥ 0.7) for p = 0.7.

In this exercise, we focus on the economic impact of the COVID-19 pandemic
Due to the COVID-19 pandemic, online teaching becomes a norm in many countries. What are the consequences of students switching to online learning in the following markets?
a) (10 points) Laptops.
b) (10 points) Classroom equipment (e.g., chairs, desks, whiteboards).
There are four markets you need to analyze separately. Assume that each market is perfectly competitive with no frictions (i.e., equilibrium point is reached with no obstacles); this gives us a permission to conduct the demand-supply analysis. In each case, start with clearly specifying who the buyers (demand) and sellers (supply) are. Then, conduct the supply-demand analysis. Provide graphical analysis in tandem with explanation.

Answer the following questions in a minimum of 500 words total.
Define Intelligence. Describe the influence of nature and nurture on intelligence: what is heritability? What do twin studies tell us about the importance of genetics on intelligence? What about how children who have been adopted and how their intelligence scores relate to their biological parents?
What are some environmental influences on intelligence?
Discuss gender differences in intelligence: do men or women have higher verbal memory? Nonverbal memory? Emotion-detecting ability? Math aptitude? Spatial ability? What does it mean to say men have greater variability in intelligence?
Finally, discuss stereotype threat and how that might affect scores on intelligence tests and in school.

As technology advances, teenagers who are online become more exposed and easier to find despite privacy measures. In a random sample, girls were less likely than boys to say that they are easy to find online from their profiles. Of 268 teenage boys with profiles, 75 say that they are easy to find online from their profiles, while out of 325 girls, 62 say they are easy to find online from their profiles.
Create a 95% confidence interval for the difference in the proportion of teenage boys who say that they are easy to find online from their profiles and that of teenage girls who say that they are easy to find online from their profiles.
Perform a hypothesis test that reflects the original aim of the experiment, at the 5% level of significance.

Introduction:
Social contract theorists say that morality consists of a set of rules governing how people should treat one another that rational beings will agree to accept for their mutual benefit, on the condition that others agree to follow these rules as well.
Hobbes runs the logic like this in the form of a logical syllogism:
Hobbes looked to the past to observe a primitive “State of Nature” in which there is no such thing as morality, and that this self-interested human nature was "nasty, brutish, and short" – a kind of perpetual state of warfare.
Locke disagreed, and set forth the view that the state exists to preserve the natural rights of its citizens. When governments fail in that task, citizens have the right – and sometimes the duty – to withdraw their support and even to rebel. Locke addressed Hobbes's claim that the state of nature was the state of war, though he attribute this claim to "some men" not to Hobbes. He refuted it by pointing to existing and real historical examples of people in a state of nature. For this purpose he regarded any people who are not subject to a common judge to resolve disputes, people who may legitimately take action themselves to punish wrong doers, as in a state of nature.
