Dr. Adriana conducts a study to determine if players who wear a new type of soccer uniform made from a specially designed fabric will perform better in soccer matches. She recruits a professional soccer team to participate in her study. She randomly assigns half of the men to wear the new material uniforms made in the color blue and the other half to wear old-material uniforms made in the colored. Although the men know about the test, they are not told which of the two uniforms is made from the new material. They are asked to wear their assigned uniforms and score as many goals as possible in a game against one another. De Adriana notes the number of goals scored. Ultimately, the players who are wearing the old uniforms score more goal and therefore, win the game, Dr. Adriana speculates that the new uniforms are not more beneficial to performance than the old uniforms, but she decides to rerun the test a few more times. From a sdentific viewpoint, why was it important for Dr. Arlana to randomly assign the players to wear new or old uniforms?
A. She wanted to make sure that the uniforms do not affect the outcome of the game played by the players.
B. she wanted the players to feel they all had a chance of wearing their old uniforms, in which they would likely be more comfortable.
C. She wanted to ensure that the performance of the players will be uniformly improved by wearing their respective unitoring
D. She wanted to ensure that each player had an equal chance of wearing the new or old uniform.

Answers

Answer 1

Answer:

She wanted to ensure that each player had an equal chance of wearing an old or new uniform.

Explanation:

The essence of random assignment or randomness in a scientific research is to avoid bais and ensure that all participants or subjects have equal chances of being in a particular category or class. In the scenario above, since half will wear the new uniform and half will el wear the old one, without random assignment, bias will set into the experiment as each of the players will not be equally likely to select either the old or new uniform. However, since the players were randomly assigned to the type of uniform, then they all have the same chance of picking either of the two categories of uniform.

Brian researched how a person's intelligence quotient (IQ) is affected by exercise. First, people took an IQ test. Then, over 2 months, they did different amounts of exercise. Then, Brian gave them a second IQ test. What is the response variable in this experiment

Answers

The question is incomplete and the full version can be found online.  

Answer: The change in IQ score from the first to second test

Explanation:

In an experiment, the response variable is the purpose of the question that is being made, while the explanatory variable is the one that has an effect over the response variable, meaning that it explains any changes in it.

If Brian is examining the effect that exercise might have on a person's intelligence quotient (IQ), the question he´s making is: does exercising change IQ results? Therefore, the change in IQ is the response variable. The amount of exercise is the explanatory variable, and the experiment aims to determine whether or not it has an effect on the response variable.

Incorrect options: The number of people in the study is the sample under study, not the response variable. The first IQ test score would be one indicator of the variable, not the variable itself. And the amount of exercise the people do is the explanatory variable, not the response variable.

specify what religion exist in Nepal and how they coexist side-by-side with unique religious tolerance and temperature​

Answers

Nepal was the last Hindu Kingdom in the whole world and the last Hindu country as well. But now it is secular and all the religions are equally treated and given same facilities however some Hindu religious sites have been strictly prohibited for the people of other religions. But talking about the religious tolerance, Nepal is an example to the whole world about it.

Firstly, here the main religions are Hinduism, Buddhism, Islam and Christianity. Even some people who are not from Hindu religion support Nepal to be Hindu country. Because there are many countries that have Buddhism or Islam or Christianity as their main religion but not Hindu country, and also the number of Hindus are decreasing day by day.

Secondly, here Hindus celebrate Id of Muslims, Muslims put red tika on the occasion of Dashain, the greatest Hindu festival in Nepal. They also visit gumbas and stupas that belong to the Buddhism. And also the people belonging to Buddhism do the same. Christians also celebrate Teej, Dashain, Tihar and all other religions celebrate Christmas. In Nepal, rather than taking their religion as a priority people take humanity and nationality as the main priority. They know how to remain in the harmony with each other.

People of different religion, regardless of the religion enjoy their happiness and share their sorrows mutually. So this best describes the religious tolerance in Nepal.

Compare and contrast modernization theory and dependency theory. Which do you think is more useful for explaining global inequality? Explain, using examples.

Answers

The correct answer to this open question is the following.

Modernization theory.

Some scholars such as Armer, the Modernization theory establishes that nations that have low-income workers have repercussions for the lack of industries and the way to improve their condition is to create the kind of industries that offer jobs and produce goods to export.

On the other hand, the Dependency theory states that the reason for inequality in a globalized world is the result of the dominion of wealthy countries that exploit the raw materials and natural resources of developing nations. This generates a dependency vicious cycle so difficult to leave by the developing nation. This country is os tied to the trade relationship with the wealthy country.

I think the Dependency theory is more useful for explaining global inequality because it clearly exemplifies how the powerful nation takes advantage of its power and wealth to keep on exploiting the natural resources of developing countries, as is the case of many developed nations that have a presence in Central America, Latin America, Africa, India, and Southeast Asia.

Globalization will continue to affect the world in the 21st century. However, more and more nations are changing their minds and had elected conservative candidates or nationalistic politicians to be their presidents. This completely changes the nature of globalization.

The dependence theory states that resources flow from a poor to a core or wealthy nation. As a result of this poor states get improvised and the rich ones are improved and the poor are integrated into the world systems.

The modernization theory is based on the process of modernization within societies. It looks at the various factors of the country before giving assistance. The theory identifies social variables that contribute to social progress. Hence the modernization theory can best explain global inequality. As it seeks human limitation, and focuses on the division of labor and democracy.

Answers

The correct answer is A) government bears an extremely heavy burden of proof to justify prior restraints.

In New York Times Co. v. the United States, the Supreme Court said that "the government bears an extremely heavy burden of proof to justify prior restraints."

In simpler terms, the United States Supreme Court established that the First Amendment to the US Constitution protected the right of the newspaper(The New York Times), to publish the Pentagon Papers.

The Pentagon Papers was the name of the copies of a U.S. military report Daniel Ellsberg released.

During the Richard Nixon presidency years, the Secretary of Defense had a series of secret documents called "the Pentagon Papers," which referred to the Vietnam War and the United States engagement from the 1940s until 1967. Ellsberg knew he had the moral obligation to share these documents with the American citizens, and he did it. So he gave a copy to the New York Times. This influential newspaper published a series of articles that shocked the nation.

Write a PEEL paragraph: Evaluate the effectiveness of being an upstander when confronted with a bullying situation
Wrong answers will be deleted

Answers

Answer:

Point: One effect of being an Upstander when confronted with a bullying situation is that it, in most cases, ends the bullying as far as the person being bullied is concerned.

Explanation:

Evidence: This happened to me when I was in third grade. I was a serial victim of one of my classmates until another classmate who had just joined the class from another school stood up to him on my behalf.

Explanation: Many bullies continue in their nefarious practices because rather than discourage their actions, others out of fear either act as their sidekick (thus joining and aiding them), endorse their action by laughing at the bullied thus acting as a reinforcer, or they simply ignore because they are either indifferent or unable to do anything about it. These are called outsiders.

Because bullies are normally used to inflicting fear and terror, they are usually taken aback and can't handle the situation (in most cases) when out of the blues, someone stands up to them.

Linkback: So because bullies have fears too, and often prey on the "weak", when anyone is brave enough to stand up to them for themselves or for another person, they usually just back down. Sometimes, out of ego, they may attempt to test the strenght of the upstander. With repeated successful resistance, they finally let go of the bullied.
