Suppose you are conducting a quantitative research study for a major car dealership in the United States with the objective to rate the importance of typical obstacles in consumers' car purchasing process (such as long wait times, complicated paperwork, aggressive salespeople, or insufficiently trained sales executives). Suppose you came to the conclusion that a random sample is not feasible or cost effective for this study. Which of the following nonprobability sampling designs (convenience sampling, judgment sampling, quota sampling, or snowball sampling) would you prefer for your study? And which of these four sampling design would be the least desirable? Please justify your assessment.

Part A: How does position in a structured hierarchy (stratification) impact quality of life? (Answer this question for inequalities on the national level for the United States)

Part B: How does position in a structured hierarchy (stratification) impact quality of life? (Answer this question for inequalities for the poor countries affected by multinational corporations)

Part C: How does position in a structured hierarchy (stratification) impact quality of life? (Answer this question for societies, but with caste structures)

Part D: How does position in a structured hierarchy (stratification) impact quality of life? (Answer this question for societies, but with with class structures)

Which of the following is NOT a potential benefit of using transgenic plants?

1. To be enforceable, every contract must include an offer and an acceptance. Consider a typical online retail transaction in which an item is ordered and paid for online by a purchaser and shipped by the seller. In two or three paragraphs, identify specifically and describe the actions that constitute the offer and the acceptance.

2. In the United States, Great Britain, and many other countries, contracts of certain types must comply with the Statute of Frauds to be enforceable. In about 100 words, describe the specific elements a contract must include to comply with the Statute of Frauds. In your answer, provide one or two examples of how each required element could be satisfied.

Lakonisho Equipment has an investment opportunity in Europe. The project costs €10.5 million and it is expected to produce cash flows of €1.7 million, €2.4 million, and €3.3 million, for years 1, 2 and 3 respectively. The current spot exchange rate is $1.36/€; the current risk-free rate in the United States is 2.3%, compared to that in Europe of 1.8%. The appropriate discount rate for the project is estimated to be 13%, the U.S. cost of capital for the company. In addition, the subsidiary can be sold at the end of the 3 years for an estimated €7.5 million. What is the NPV of the project? What is the IRR of the project? Should Lakonisho Invest in this project?

The technology underlying hip replacements has changed as these operations have become more popular (over 250,000 in the United States in 2008). Starting in 2003, highly durable ceramic hips were marketed. Unfortunately, for too many patients the increased durability has been counterbalanced by an increased incidence of squeaking. An article reported that in one study of 146 individuals who received ceramic hips between 2003 and 2005, 13 of the hips developed squeaking.

(a) Calculate a lower confidence bound at the 95% confidence level for the true proportion of such hips that develop squeaking. (Round your answer to three decimal places.)

It has been proposed that lightning be harvested for energy. Measurements of lightning strikes indicate that they have the following average properties (note, these are reasonable approximations):

• Potential difference between each end of 100 million V

• Current of 30000 A

• Time of 1.67E-4 seconds

• 20 strikes per square kilometer per year in lightning prone regions of the United States and 200 strikes per square kilometer per year in the most lightning prone regions in the world (Congo).

"Lightning collectors" are devices which have the following properties (I'm just making these up, though I think they are wildly optimistic):

• They can only collect lightning that would strike within a 100 m x 100 m area

• They each cost $10,000

• They last 40 years

• Maintenance costs and scrap value are negligible

The following economic data are also known (these are very rough estimations):

• Electrical energy is worth about $0.17 per kWh and is not expected to increase in value

• Investors in such projects expect to get back triple their initial investment in total after 40 years

As an independent energy consultant, it is your job to check if this project is a good investment in either the United States or Congo. Provide a report detailing your assertions and your reasoning. Assume that your audience is investors who have perhaps taken high school physics or college physics many years ago. You will be graded on both the correctness of your physics (and accounting) and your ability to explain the physics to such an audience.

vaccine hesitancy among parents (for their children) as well as among adults (for themselves) exists in the United States which may limit the country's ability to control the COVID-19 pandemic in the United States. As a health psychologist, you have been given the job of using a theory of health behavior change to design a multi-level public intervention to increase the rate of COVID-19 vaccine uptake once it has been found to be effective. Using one or more theories of health behavior change (see Health Behavior Theories in Gurung, please briefly describe 3 behavior change strategies that encompass multiple levels including strategies that, 1) medical and other social service providers can use with individual patients/families to get them to get the vaccine and/or vaccinate their children; 2) social strategies, including strategies for changing social norms about the benefits of getting the vaccine, and 3) structural strategies including ease of obtaining the vaccine such as the availability, price, amount of time required, etc. Please be specific regarding which theory (or theories) you are using and the corresponding strategy. For example, using the Theory of Planned Behavior, you might focus on changing parental attitudes about getting the vaccine by creating an instagram posts/videos for parents that focus on the way they value their children's education. The video would demonstrate that by getting the vaccine, it will enable their child - and their child's friends - to be able to attend school in-person. Describe 3 health behavior strategies and the corresponding theory of health behavior change for increasing the uptake of the potential COVID-19 vaccine.

Over the past decade, the federal government has taken significant steps to encourage the development of ethanol and other fuels made from plants as a partial replacement for gasoline. These actions have been undertaken by politicians in the midst of public concerns about the dependence on foreign oil, war in the Middle East, and global warming. The primary input for ethanol production is corn. In 2011, the 13.9 billion gallons of ethanol produced in the United States consumed over 20 percent of the domestic corn supply. Suppose that the government has just passed new legislation mandating increased annual pro- duction of corn ethanol. You manage the Hog Heaven restaurant chain. Your restaurant chain, which has about 300 outlets throughout the United States, specializes in barbecue pork dishes but also offers chicken, beef, and vegetarian meals. Currently about 80 percent of your revenue comes from your pork dishes. The price of pork has a major impact on your costs. You are concerned that the federal promotion of ethanol might have an impact on pork prices and the profitability of your restaurant chain. Feed cost is typically about 50 to 60 percent of the total cost of production of pork producers. About 80 percent of the feed that hogs consume is corn.

Use basic supply and demand analysis to illustrate the likely effect of the government’s man- dated increase of ethanol production on (1) corn prices and (2) pork prices and What actions might you consider given the results of your analysis?
