When a person makes a moral decision based on wanting to make sure that the decision is acceptable in the community, the person's moral reasoning is at the ________ level.

Answers

Answer:

Conventional.

Explanation:

This was been propounded by Lawrence Kohlberg where it was explained to have different levels of reasoning. The conventional falls in as the second level of the many stages of reasoning. During this level, a child's reasoning is said to be tied to some traditional and mostly societal reasonings. Also during this conventional level, a child’s sense of morality is tied to personal and other factors that show relationships to his reasoning. It is seen that in this stage children seem to continue to accept the rules of authority figures, which is primarily based on the belief that this is necessary in keeping up their positive relationships and order in the society they find themselves.

The philosophies of John Locke and Robert Nozick can be said to diverge in which of the following respects: a) Nozick defends strict constraints on what the majority can do whereas Locke defends no constraints. b) Locke derives individual rights from the good of society as a whole, whereas Nozick derives rights from individual self-ownership. c) For Locke, the right to life is inalienable, whereas for Nozick, the right may be surrendered by its possessor. d) Nozick defends a pre-political (natural) right to property whereas Locke does not. e) Locke claims that the purpose of government is to secure rights, whereas Nozick claims that its purpose is to secure wealth.

Correct Answer:

e) Locke claims that the purpose of government is to secure rights, whereas Nozick claims that its purpose is to secure wealth.

Explanation:

John Locke and Robert Nozick are two different philosophers who hold different views regarding to humans. For John Locke, he argued that all persons are endowed with natural rights to life, liberty, and property and that rulers who fail to protect those rights may be removed by the people, by force if necessary.

Since there is a relationship between output and input when measuring productivity, the following relationships may occur: Productivity increases when new and improved capital goods are used to produce other goods and services. The development of technology certainly contributes to the increase in productivity (because it promotes the development and implementation of better machinery and equipment.) Due to technological development and growth workers can produce equivalent goods and services in less time. Work the same amount on goods and services.

Most US adults have social ties with a large number of people, including friends, family, co-workers, and other acquaintances.

Does the sample provide evidence that the average number of social ties for a cell phone user is significantly different from , the hypothesized number for all US adults?

Answers

Hello. This question is incomplete. The full question is:

Most US adults have social ties with a large number of people, including friends, family, co-workers, and other acquaintances. It is nearly impossible for most people to reliably list all the people they know, but using a mathematical model, social analysts estimate that, on average, a US adult has social ties with 634 people.1 A survey of 1700 randomly selected US adults who are cell phone users finds that the average number of social ties for the cell phone users in the sample was 664 with a standard deviation of 778. Does the sample provide evidence that the average number of social ties for a cell phone user is significantly different from 634, the hypothesized number for all US adults?

Answer:

The sample does not provide evidence that the average number of social ties for a cell phone user is significantly different from 634.

Explanation:

First, it is necessary to find out if the average number of social connections for a cell phone user is significantly different from 634 people. For this, we will consider:

H₀: The average number of social connections for a cell phone user is 634 people. For this we will use μ = 634.

Hₐ: The average number of social connections for a cell phone user is different from 634 people. For this we will use μ ≠ 634.

After these considerations we will adopt the following information:

n = 1700

'X = 664

SD = 778

We can see that the size of the sample is very large and as the population is unknown, we will use the concepts of the central limit theorem and adopt the average sample distribution in the same way as the normal distribution. For this reason, a single mean z test will be appropriate in this case.

After understanding the information, we can calculate the test value. For this it will be necessary to use the formula:

z= ('x-μ)/(SD/√n)

z =(664-663)/(778/√1700) = 1.59

When finding this value, you must take into account whether the p-value of the test is less than the significance level.

The p-value for the two-tailed test is found by the formula:

p - value = 2 * P (Z> 1.59)

p - Value = 2 [1-P (Z> 1.59)

p- value = 2 * (1-0.944) = 0.112

The p-test reveals a very high value in relation to the level of significance and shows that the null hypothesis must be rejected. Based on this, we can say that we have no factor that proves that the average number of social connections for a cell phone user is different from 634 people.

Answers

The correct answer to this open question is the following.

Although the question does not include options, we can say the following.

Since the probability that a new marriage will end in divorce varies based on whether either of the newly-weds has been divorced before, these two outcomes (the fate of the new marriage and the previous divorce record of the newly-weds) are dependent.

The variables are dependent because they influence the faith of the new couple when getting married. If one had the unfortunate experience of the divorce in its previous relationship, it could impact the direction of its new marriage. It cannot be mutually exclusive because this term means that the events cannot happen at the same moment.

In five ways examine validity of the statement that "a country without a constitution has no future for its populace, especially the youth."​

Answers

Answer:

No justice No education system for youthNo restriction on criminals Destroy society Destroy economy

Explanation:

The Constitution is the source of law and order. If there is no law in the country, the situation of the society will deteriorate further. Justice was not done and the accused were released. Without the constitution, the people would have no law and the criminals would be free and the youth of the country would also commit crimes. Without a constitution the country will not last long. The Constitution of the country provides an education system for the youth so that the youth are illiterate without a constitution. The constitution prohibits people from doing bad things and maintaining peace in society. Countries that do not have an constitution make their people wild like animals because there is no limit on them. It will also destroy the country’s economic situation leading to youth unemployment.

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

The loci method is a strategy to memorize better that consists of mentally associating an image with a certain place, that is, it consists of visualizing what we want to memorize and the “place” in which we keep it, establishing relationships between the contents and the images we generate from them. This implies that each content to be memorized is going to become a mental image that can be “seen” in the memory palace, with its spatial location and the rest of the objects (contents) related to it. The student has associated specific data with specific three-dimensional spaces, in this way it will be easier to remember it and to be able to use the information in an easy and accessible way.

Which quotation from this passage best states a theme of the story? “My magic did not help me at all and yet there was a fire in my bowels, a fire in my mind.” “When the sun rose, I thought, ‘My journey has been clean.

Answers

Answer:

Hm..Not sure how to answer this, but I think the quote that states the theme of the story you're reading is, "When the sun rose, I thought, 'My journey has been clean, now I will go home from my journey.'"

Explanation:

The other quote I would go with is, "My magic did not help me at all, and yet there was a fire in my bowels, a fire in my mind." However, this particular quote did not make quite enough sense to me; yes, you have fire in your mind and bowels, but why? It just didn't make much sense to me.

 

The quote, "The Forest People themselves do not come near" quote was just..vague to me. To be completely honest, I was wondering about the Forest People themselves, and what exact thing or place that they wouldn't approach at all.

Lastly, the quote, "If I went to the Place of the Gods, I would surely die, but if I did not go, I could never be at peace with my spirit again," was kind of a statement. I read it a couple of times thinking, 'hm..this could sound like a theme just a bit, if only the sentence didn't sound like a statement the character of the story had made.'  Also, to be completely honest, I don't think this quote could state a theme of any kind.

I hope that this helps.

In order to study the effects of loud noise on worker productivity, Dr. McDuffee had one group of research participants work in a noisy room and a second group work in a quiet room. Those who worked in the quiet room were exposed to the________ condition

A) experimental

B) survey

C) control

D) correlational

The correct answer is C. control condition

Explanation:

In an experiment, it is common one group receives a special treatment, which is known as "experimental condition", while the other group does not receive this treatment, this condition is known as the control condition. Moreover, the control condition is relevant in the research because it can serve as a comparison to the experimental condition or special treatment.

In the case presented, the experimental condition would be the noisy room because this is the variable the researcher is studying in reference to worker productivity. Also, those who are not in the noisy or those in the quiet room are exposed to the control condition because they do not receive the treatment but serve a control to measure the changes in productivity in a noisy room.
