A paper described a survey of 501 undergraduate students at a state university in the southwestern region of the United States. Each student in the sample was classified according to class standing (freshman, sophomore, junior, or senior) and body art category (body piercings only, tattoos only, both tattoos and body piercings, no body art).
Use the data in the accompanying table to determine if there is evidence of an association between class standing and response to the body art question. Assume that it is reasonable to regard the sample of students as representative of the students at this university. Use
α = 0.01.

16.5 Ethics Case M.R. Watters was the majority shareholder of several closely held corporations, including Wildhorn Ranch, Inc. (Wildhorn). All these businesses were run out of Watters’s home in Rocky Ford, Colorado. Wildhorn operated a resort called the Wildhorn Ranch Resort in Teller County, Colorado. Although Watters claimed that the ranch was owned by the corporation, the deed for the property listed Watters as the owner. Watters paid little attention to corporate formalities, holding corporate meetings at his house, never taking minutes of those meetings, and paying the debts of one corporation with the assets of another. During a vacation visit, two guests of Wildhorn Ranch Resort drowned while operating a paddleboat at the ranch. The family of the deceased guests sued Watters to recover from Watters. Is Watters personally liable in this case? Geringer v. Wildhorn Ranch, Inc., 706 F.Supp. 1442, 1988 U.S. Dist. Lexis 15701 (United States District Court for the District of Colorado)

Suppose Canada can produce 20 units of Oil and 0 units of potatoes if it chooses to only produce Oil. Otherwise, Canada can produce 50 potatoes and 0 units of oil if it only chooses to produce potatoes. The United States on the other hand can produce 25 units of oil (and 0 units of potatoes) if it choose to produce only oil and 100 units of potatoes and 0 units of oil if it chooses to produce only potatoes.
A.) What is the opportunity cost of 1 potato for the U.S.? For Canada?
B.) What is the opportunity cost of 1 oil for the U.S.? For Canada?
C.) Who has the absolute advantage in the production of Oil? Potatoes?
D.) Who has the comparative advantage in the production of Oil? Potatoes?
E.) Suppose the U.S. has decided to be self sufficient and is producing 10 units of oil and 40 units of potatoes. Is there anyway that the U.S. increase its consumption of goods outside its production possibilities frontier (for example, consume more potatoes without changing the consumption of oil)?

Are Future Budget Deficits a Threat to the Economy?
Congress gives the Congressional Budget Office (CBO) the responsibility of estimating the effects of federal spending and taxing policies on the economy. An Associated Press news story on a CBO report noted that federal budget deficits in the United States were likely to increase in future years. According to the CBO, these higher deficits might "pose a threat to the economy by crowding out business investment and threatening a spike in interest rates."
(Source: Andrew Taylor, "CBO: Deficits to Drift Lower on Lower Health Costs," Associated Press, April 14, 2014.)
a. What did the CBO mean by a "spike in interest rates"? Why might increased federal budget deficits lead to a spike in interest rates? Illustrate your answer with a graph.
b. Is the spike in interest rates connected to crowding
out? Why might crowding out be considered a threat to the economy?
