Answer:

100−140

Explanation:

The normal distribution has two parameters:

The mean \mu

The standard deviation \sigma.

It can be called N(\mu, \sigma).

The 68-95-99.7 rule indicates that:

68% of the measures are within 1 standard deviation of the mean.

95% of the measures are within 2 standard deviations of the mean.

99.7% of the measures are within 3 standard deviations of the mean.

In this problem, we have that:

N(120,20).

This means that the middle 68% of people in this group score on the test are in the range of 120-20 = 100 to 120+20 = 140.

Project: International Organizations Post WWII?
Dovator [93]

Answer:

1. World War II led to a renewed interest in international efforts to maintain peace. Explain the specific reasons and historical events that led to the creation of the United Nations. How did the United Nations differ from the League of Nations?

World Wars, genocides, revolutions, continued disarray and instability amongst and within nations, and various other situations led to the creation of the United Nations. One more important factor which led to the creation of the United Nations was increased demand for equality and freedom which led to decolonization in the late 1900s. As a result, the United Nations was created with the sole purpose of preventing further chaos worldwide through diplomacy and to promote human rights as a path towards maintaining peace. The League of Nations was created following The First World War and although it laid the foundation for the United Nations, it focused on preventing further large-scale conflicts through diplomacy, while the United Nations focuses on promoting international peace and justice as a backbone to prevent mass conflicts.  

2. How successful has the United Nations been in reaching its goals? Cite the failure of the UN as evidenced by the sources in the appendix.

Although the United Nations has been promoting peace and justice through the world by way of numerous peace keeping organizations and the Declaration of Human Rights, the United Nations has seen failures in reaching its goals. Rwanda is one example of the United Nations terrible effort at maintaining peace in the region. The UNAMIR was sent as the body to aid in preventing the genocide, but the results of that intervention are well known as the Rwandan genocide did in fact occur killing 500,000 to 800,000 members of the Tutsi clan. UN Secretary-General Kofi A. Annan reports on the organization of the entire mission as a whole which lacked cooperation, a cohesive plan, general set-up of the peace keeping troops, including a lack in the number of troops sent to Rwanda in accordance to the actual number suggested by field experts.  

3. Internationalism continued to grow after World War II. Explain the purpose and goals of the World Bank and the International Monetary Fund.

As a result of the Great Depression, which was a very encouraging factor of World War II, internationalism grew to great extents and led to the establishment of a substantial number of organizations formed. The World Bank and the International Monetary Fund have a shared purpose of working towards maintaining economic stability. As trade advanced, countless opportunities started to become available for the common man, yet nearly a billion people around the world in 2007, were living on $1 a day. The World Bank was tasked with the responsibility to make those opportunities more accessible to the billion people around the world living in poverty. The consequences of both World Wars included large amounts of economic loss on nations, more specifically to the nations directly involved in the wars. The International Monetary fund was created to establish and maintain stable postwar economies for the aforementioned nations.  

4. The European Economic Community was established in 1957. This organization was later renamed and extended into the European Union. What were the goals of this economic alliance? How successful has the EU been in reaching its goals?

The European Europe also known by its former name, the European Economic Community, aimed to establish a common trade market amongst member nations and encouraging peace through economy and politics for European nations after the fallout of World War II. They believed that the causes of the Great Depression were brought about by the restrained trade policies and lack of cooperation and unity between nations. Boosting the economies of member nations through a common trade market was the goal of this economic alliance. The EU has been successful in reaching its goals through free trade flow across EU borders while establishing the Banking Union to ensure safer and more reliable banks following the Financial Crisis of 2007-2008. A more profound proof of the European Union’s success in maintaining economic stability and free trade among member nations would be their achievement of gaining the Nobel Peace Prize in 2012.
