"Selection bias " is the correct answer.

Explanation:

Selection bias seems to be a statistical prejudice from which a mistake arises in determining the individuals to participate throughout a research sample. The selection effect has often been started referring to each other like this.The significant problem would be that personal-selection seems to be a particular activity that can overlap with certain similar behaviors and this study sometimes doesn't represent the overall population.

Answers

Answer:

USSR

Explanation:

Answer:1955

May 14

The Warsaw Pact is formed

The Soviet Union and seven of its European satellites sign a treaty establishing the Warsaw Pact, a mutual defense organization that put the Soviets in command of the armed forces of the member states.

The Warsaw Pact, so named because the treaty was signed in Warsaw, included the Soviet Union, Albania, Poland, Romania, Hungary, East Germany, Czechoslovakia and Bulgaria as members. The treaty called on the member states to come to the defense of any member attacked by an outside force and it set up a unified military command under Marshal Ivan S. Konev of the Soviet Union. The introduction to the treaty establishing the Warsaw Pact indicated the reason for its existence. This revolved around “Western Germany, which is being remilitarized, and her inclusion in the North Atlantic bloc, which increases the danger of a new war and creates a threat to the national security of peace-loving states.” This passage referred to the decision by the United States and the other members of the North Atlantic Treaty Organization (NATO) on May 9, 1955 to make West Germany a member of NATO and allow that nation to remilitarize. The Soviets obviously saw this as a direct threat and responded with the Warsaw Pact

Hey there! I'm happy to help!

Natural rights are rights you have just from being a person. They can also be thought of as universal rights, basic rights, or even unalienable rights, as seen in the Declaration of Independence. They wanted to have their rights such as life, liberty, and the pursuit of happiness available to them, but such heavy rule and taxation from England, this was especially difficult. The Pilgrims and Puritans fled from England because they disagreed with the Church of England, which was being heavily pushed at the time. In America, they did not wanting the country they fled due to religious to be ruling over them and threatening their natural right to be free to choose whatever religion they wanted. These things and many more led them to move towards revolution.

The correct answer to this open question is the following.

Although there are no options provided, we can say the following.

An officer receives an anonymous tip that controlled substances are being transferred in a particular vehicle to a particular place. This is the only information the officer has on the matter. The best course of action would be for the officer to immediately attempt to corroborate if the tip was true or just a rumor.

what are the importance of literature review​

Answers

Answer:The literature review performs a number of

important functions:

• It demonstrates to a Ph.D. committee that the student has read a large amount of

statistical literature to prove that the student is aware of the wide range of research

in theory and methodology related to the proposed research topic.

• It provides proof to a Ph.D. committee that the student has an deep understanding of

the published statistical research related to the topic of the dissertation.

• It should convince the Ph.D. committee that the student can communicate this understanding of the statistical literature and its relationship to the proposed research.

• It should support the originality and relevance for the Ph.D. research problem.

– This is done by identifying specific gaps in the statistical literature. That is, the

student identifies statistical questions that have not been answered and problems

that have not been solved.

– By identifying gaps in the statistical literature, the student can justify the originality of the proposed dissertation research. The originality can be an extension

of research that has been published or a modification of existing methodology or

theory that can be used to perform the Ph.D. research.

• In the proposal you will emphasize or stress the originality of the dissertation. Without a good literature review, you cannot convince your committee that that the proposed research is original.

• A dissertation may be unacceptable because the Ph.D. student does not clearly show

that the research problem is original due to a poor literature review.

• Remember: the Literature Review is more than a summary of publications. It provides

evidence that your research will be an original and relevant contribution to statistics.

When the researcher's expectations influence participant's behavior and/or the researcher's interpretation of the experimental results, it is called ____

Answers

Answer: Experimenter Bias

Explanation:

Experimenter bias is a phenomenon in research where the researcher influences the behavior of participants and/or the researcher's interpretation of the experimental results. This is because as humans it is almost impossible to be objective due to the feelings and emotions we have about certain thoughts and actions and as a result, these feelings and biases are mirrored into the research thereby reducing the accuracy of said research.

More often than not, this bias is unconscious which makes it even more deadly because it will be harder to detect by the researcher who will then be unable to take countermeasures to mitigate the effects.

This question is incomplete because the options are missing, here is the complete question:

During the Middle Ages, many villages had areas reserved for families to take their cows or sheep to graze. All families were welcome to use this land without charge. This situation likely led to a(n):

A. finite of proportions.

B. tragedy of the commons.

C. marketable public good.

D. exhaustive equilibrium.

The answer to this question is B. Tragedy of the commons

Explanation:

A tragedy of the commons is a phenomenon that occurs when a common or public resource is depleted or destroyed due to individual interests. Besides this, a tragedy of the commons is the result of overconsumption and not considering collective interests.

This phenomenon likely occurred in the case presented because it is likely each family that owned sheep or cows only thought about its interest and tried to use the common good (areas to graze) as much as possible, without considering others' right to use it or the collective interest of preserving the area. This likely led to the depletion of the resource, and therefore a tragedy of the commons.

An industry has 5 firms, and is found to have violated antitrust laws. The government breaks it up into 10 firms that will share the market equally. As a result of this government action, the Herfindahl index for the industry would change from: to .

Answers

Answer:

2,000 to 1,000

Explanation:

The Herfindahl-Hirschman Index, HHI, is measured by using the market share of each firm in the industry, then square them, and sum the result.

However, supposing that there were only one firm in an industry, that firm would have 100% market share, and the Herfindahl-Hirschman Index (HHI) would equal 10,000, indicating a monopoly.

Thus, in this case, it was initially 5 firms, with no special market share allocated to each of the firm, hence, it is assumed they shared the market share equally, and that will be 2,000 HHI. This shown by each of the 5 firms having 20% market share

HHI = 20² + 20² + 20² + 20² + 20² = 2,000

At the same time, since the government breaks the industry up into 10 firms that will share the market equally. Then, the Herfindahl index will be 1,000. This is shown by HHI = 10² * 10 (since it involves 10 firms with equal share of the market) = 1,000.

Therefore, The Herfindahl index for the industry would change from: 2,000 to 1,000.
