Answer:

There is a high positive correlation between sleep and exam performance

Explanation:

Correlation studies the degree of association between two variables. A correlation coefficient of 0.5 to 1 is regarded as a strong correlation, that is an increase in one variable will result in an increase in the other variable. A correlation coefficient that lies between 0.3 to 0.49 is regarded as moderately correlated while a value of 0 means that there is no correlation.

Thus, the result of this study shows that an increase in sleeping time will result in better exam performance.

Pavel [41]

The statement is True. The communication and technological revolution that promotes and enables the globalization of culture has eliminated the preservation of cultural diversity.

Cultural diversity is set appreciating that society is made of many distinct corporations with special pursuits, talents, competencies and. Wishes. It additionally means that you realize that human beings in society can have different religious ideals and sexual orientations to you.

It facilitates dispelling negative stereotypes and private biases about specific companies. Similarly, cultural diversity helps us apprehend and appreciate “approaches of being” that are not always our personal. In order as we engage with others, we will build bridges to consider, respect, and know-how across cultures.

ehidna [41]

Answer:

(a)The congress could pass a bill by stopping medications of life-or death from being increased to a particular value, thereby making Mylan to reduce their prices, to a more tangible value (b) If the president is not part of this decision, he can use his veto powers against the bill passed by the congress, thereby making Mylan to retain their rates as high as it is currently (c) Lobbyist and Interest groups will further express their ideas towards the president and congressmen to hold on, or make a change in the bill.

Explanation:

Solution:

(a) Congress could pass a bill by stopping important life-or-death medications from being added up above a certain value. in doing so,Mylan would be  made  to lower their prices to a more sensible value.

(b) If the President is not in approval of this sort of law making, he can use the power of veto towards the  bill passed by Congress, in doing so Mylan can keep their rates as high as present as it is now. As a result, the power of Congress is weakened by the President's own power.

(c) For them to push their ideas forward, many lobbyists  and interest groups would likely meet with the president and congressmen encouraging  them to either or hold firm or make a change in their position on the bill such as lobbying  several organizations that fight for the right of victims would urge congress to disallow a presidential veto of the bill this would mean that if they vote to override the veto, the bill becomes a law.
