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.

(Hand written not allowed)

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:

1. We are all self-interested.
2. Each of us needs to have a peaceful and cooperative social order to pursue our interests.
3. We need moral rules in order to establish and maintain a cooperative social order.
4. Therefore, self-interest motivates us to establish moral rules.

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.

Instructions:

• Which philosophy do you espouse?
• How much authority should be granted to governments (e.g., the right to kill (death penalty/capital punishment/use of deadly force)? How much would you give up in return for safety?
• If you side with Hobbes, do you support at any point recourse if the government violates its own contract (if so, you probably have a bit of Locke in your thinking)?

Please type down your response after reading the paragraphs.  (at least 5 sentences long, 150-200 words)

I think this is a very controversial topic but also, an hypothetical one. Who knows if everything could turn out fine and make this one of the greatest innovations of all time? Who knows if it's going to be a 'failure'?

In my point of view, dealing with AI is tricky. I feel that nothing should ever be done to reach the limits, specially when dealing with technology. However, it has to be done between the limits and be controllable. In the video, Sam Harris tells us that year after year we will improve our machines and eventually build machines that are way smarter than we are and that, eventually, they can improve by themselves. At this point, I feel like we've already crossed our limit and are susceptible to have an "intelligence explosion" and get this situation out of control. In this sensitive scenario, we should opt for the safer option and take our time to reevaluate our improvements so far and make it a slow process so that we can assure that none mistake or action is taken that can harm us in the future.

At this point and when talking about AI, risks and safety should always be concerning and always going to be present. As a consequence, our generation should realize that this is a big deal and reflect about it and decide (each time they want to make another improvement) if the risks that they are going to take are worth threatening our future existence and safety. In conclusion, I don't think there's a yes or no to this question and topic. However, it's definitely something that, in my point of view, needs to take its time and constantly reevaluate our situation, improvements, risks, but more importantly, our safety in a near future.

Create a supply and demand graph illustrating the scenario, the shock, and the predicted effects on wages and employment:

Scenario #1

Airbnb has housed over 150 million guests in over 65,000 cities since 2008. Do a bit of research on what Airbnb is and how cities and the hotel industry has been responding to it. Using standard supply and demand graphs from the course, model the labor market for hotel workers, pre-Airbnb, and show how Airbnb has likely affected the market.

Scenario #2

We all love to go to little, local ice cream shops. Many of these places hire teenagers over the summer to serve these delicious treats for us. Suppose that a new minimum wage bill comes online this summer, raising the minimum to $10/hour. Create two graphs: 1) model the market for these ice cream shop workers and how shop owners will likely respond to the minimum wage increase immediately after it happens; 2) model what would happen if a company starts using very cheap robot ice cream servers.

Scenario #3

Research and find specific examples of immigrants working as a) substitutes for U.S. workers and b) compliments to U.S. workers. Make sure you put the correct graph with each story.

Scenario #4

Many parts of the U.S. have a shortage of IT workers... not enough people are trained in these fields. Model the market for IT workers. What would happen if a new training program was targeted toward people in Appalachia who have a hard time finding work... the program trains this group to be IT technicians.

Scenario #5

You are looking at the labor market for young, childless males seeking work with low-paying employers (i.e. Wal-Mart). With a supply and demand graph, show the effects of expanding the EITC to these workers. Illustrate an initial equilibrium (before EITC), the shift due to the new EITC expansion, and point out the wage they get paid from the employer and the additional “pay” they get due to the EITC.
