After the end of the Cold War, NATO 1 ptsQuestion 2 security is a collective action problem. states cannot normally agree on what constitutes a threat to peace. their organizational structure often prohibits the use of force by the organization. All of these Collective security organizations are often unable to prevent the outbreak of conflict because 1 ptsQuestion 3 They increase the cost of conflict, making violence less likely. They increase the likelihood of war by forcing states to take positions they might otherwise not take. They increase the likelihood of conflict by reducing its cost. How do credible alliances affect bargaining in the international system? They reduce the likelihood of conflict by reducing the effective number of actors in the international system. 1 ptsQuestion 4 The number of peacekeeping missions decreased. The number of permanent members increased. The number of vetoes decreased. Security Council activity was largely unaffected by the Cold War's end. How was UN Security Council activity affected by the end of the Cold War? 1 ptsQuestion 5 alliances; they are based on more credible shared interests alliances; they can reduce the threat of violence without relying on the use of countervailing force collective security organizations; they are based on more credible shared interests collective security organizations; they can reduce the threat of violence without relying on the use of countervailing force In general, _______________ are more effective in reducing the risk of violence between countries because ____________. 1 ptsQuestion 6 economically. militarily. politically. In international relations, an alliance is an institution that helps countries cooperate scientifically. 1 ptsQuestion 7 the five main committees of the United Nations. the five key advisers to the Secretary General. the five permanent members of the Security Council. the bureaucracy and officers responsible for organizing the UN's activities. In the context of the United Nations, the P-5 refers to 1 ptsQuestion 8 preventing the outbreak of internal conflicts (civil wars) within states preventing inter-state conflict and ending hostilities between states preventing genocide post-conflict reconstruction and development In which area have United Nations peacekeeping operations been most successful? 1 ptsQuestion 9 failed to keep peace. succeeded in preventing cease-fires from being violated. increased the likelihood of a new civil war breaking out. required little effort by participating countries. On average, peacekeeping has 1 ptsQuestion 10 has the consent of the warring parties. is used to enforce a peace treaty. often does not have the consent of the warring parties. does not require the use of force in order to participate. Peace enforcement 1 ptsQuestion 11 China; Russia France; Great Britain France; Russia China; Great Britain The United Nations Security Council has generally hesitated to define domestic conflicts as a "threat to international peace and security" primarily because _________ and ________ have used their veto power to block interventions in domestic affairs. 1 ptsQuestion 12 to make sure that each side has an even amount of power. to match a joint rival militarily. to dominate a joint rival militarily. if their partners are equal in power. The balance-of-power theory of alliance formation argues that states are more likely to join an alliance 1 ptsQuestion 13 an institutional arrangement for regulating the global financial system an institution that implements immigration policies an institution where all members are responsible for addressing aggression a system of voting on the use of force within the United Nations What is a collective security institution? 1 ptsQuestion 14 attacking a weak state provoking a strong state joining the weaker side in a conflict joining the stronger side in a conflict What is bandwagoning? 1 ptsQuestion 15 Alliances are generally more formal and have clearer decision-making structures than collective security organizations. Alliances are generally smaller and involve more like-minded states than collective security organizations. Alliances are generally larger and bring together a greater diversity of states than collective security organizations. What is the most significant difference between collective security organizations and alliances? Alliances are generally informally organized and lack the clear decision-making structures present in collective security organizations. 1 ptsQuestion 16 the General Assembly the International Court of Justice the Economic and Social Council the Security Council Which body of the United Nations gives some members the ability to veto resolutions? 1 ptsQuestion 17 Bangladesh Ghana the United States Germany Which country is the top contributor of peacekeeping soldiers to United Nations' operations? 1 ptsQuestion 18 the North Atlantic Treaty Organization (NATO) the United Nations (UN) the World Trade Organization (WTO) Which of the following is an example of a collective security organization? Quiz saved at 9:00pm the International Maritime Organization (IMO) 1 ptsQuestion 19 expunging nuclear weapons from a country resolving a border dispute punishing an aggressor deploying troops to monitor a cease-fire Which of the following is an example of peacekeeping? 1 ptsQuestion 20 States sometimes engage in bandwagoning behavior rather than seeking to balance power. State decisions are sometimes motivated by non-power considerations like ideology or religion. The distribution of power in the world is itself unbalanced, making finding partners to balance power difficult. All of these Why is balance-of-power theory unable to fully account for the decision of states to join a particular alliance? Submit Quiz MA3110: Module 5 Chi Square and Anova Exercise 5.1 Inferences from Two Samples 1 This exercise has the following two tasks: Task 1: Consider the three samples listed in the table: A B C · Obtain the sample mean and the sample standard deviation of each of the three samples. · Obtain total sum of squares (SST, treatment sum of squares (SSTR), and error sum of squares (SSE) by using the defining formulas and verify that the one-way ANOVA identity holds. · Obtain SST, SSTR, and SSE by using the computing formulas. · Construct the one-way ANOVA table. Task 2: Read the case study titled “Losses to Robbery” and answer the corresponding questions: Losses to Robbery: The Federal Bureau of Investigation conducts surveys to obtain information on the value of losses from various types of robberies. The results of the surveys are published in Population-at-Risk Rates and Selected Crime Indicators. Independent simple random samples of reports for three types of robberies—highway, gas station, and convenience store—gave the following data, in dollars, on the value of losses. Highway Gas Station Convenience Store MA3110: Module 5 Chi Square and Anova Exercise 5.1 Inferences from Two Samples 2 Highway Gas Station Convenience Store · What does treatment mean square (MSTR) measure? · What does error mean square (MSE) measure? · Suppose that you want to perform a one-way ANOVA to compare the mean losses among the three types of robberies. What conditions are necessary? How crucial are those conditions? · Show detailed steps and provide appropriate rationale with your answers.
