Answer 1

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.

Educational objectives should guide classroom activities and evaluation. To accomplish this effectively, the objectives should be:

Answers

Answer:

stated in terms of specific observable behavior.

Explanation:

Educational objectives refer to the standards set either by educational institutions or individuals to guide the study of the peoples. Such goals should represent the educational expectations of both teachers and students as well as the quality of the curriculum program. Besides that, widely used assessment methods, while likely providing a way of awarding ratings, also do not provide sufficient input to assess whether students are meeting the assigned goals. This is generally dependent on a blend of not having structured objectives, to begin with, not having converted those goals into observable results, and not using evaluation methods that are capable of assessing anticipated educational outcomes given the level of skill required to improve them.

Describe in a brief paragraph one of the seven major religions in the world and how it can exist in our United States culture. Is secularization (the different forms of religion in our culture) of religion a good or dysfunctional part of our overall culture today?

Answers

Answer:

Hinduism is one of the most ancient religions in the world. The religion is enriched with the best possible spiritual facets and reflects the ideal ways to live this very life.

Hinduism has spread fascinating and crucial aspects like four "Vedas" (Rigveda, Yajurveda, Samveda, Atharv Veda), four ashrams/ stages of life (Brahmacharyashram, Grihastashram, Vanprathashram and Sanysashram which mean studenthood, family/ social life, retirement and getting detached from the materialistic life).

In the United States, numerous people work in the Software industry who are from India and on other hand, organizations like Ramkrishna Math, Akshardham and ISKON have cultivated human beings for holistic development.

The principle of "Adwaita" (Oneness) is the backbone of Hinduism which can be found being practiced by a good number of Americans. Yoga, meditation, and Namasmaran (chanting) are other ways that have their roots in Hinduism and have blossomed the life of the native Americans too.

Secularisation of religion is fine until it does not alter and violate the essence and identity of a specific religion. But if the secularisation attempt disturbs the rhythm of religion, it should be avoided.

Beltram's memory loss is probably due to: a. Dissociative Fuge b. Alzheimer's Disease c. Dissociative Identity Disorder d. Korsakoff's Syndrome

Answers

The correct answer is D) Korsakoff's Syndrome.

Beltram's memory loss is probably due to Korsakoff's Syndrome.

The question clearly says that Beltram is currently 61 and has been a heavy drinker his entire life. Lately, he has started to have serious memory problems. So we cannot consider it Alzheimer's Disease.

Due to the heavy drinking problem, what Beltram has is Korsakoff's Syndrome. It is a memory disorder due to the deficiency in the body of vitamin B-1, or thiamine. And precisely heavy drinking can be a cause of the syndrome because of the toxic effect of alcohol in the cells of the brain.

You are spending the month of July hiking and biking in the Rocky Mountains, in the western US state of Colorado. Based on concepts covered in chapter 9, explain why you would typically plan your daily rides and hikes in the morning hours to minimize the chances of being caught in bad weather.

Answers

The correct answer to this open question is the following.

Although the question does not include the concepts covered in chapter 9 or any other reference, we can comment on the following.

You would typically plan your daily rides and hikes in the morning hours to minimize the chances of being caught in bad weather because in the month of July hiking and biking in the Rocky Mountains, in the western US state of Colorado could be a great experience during the mornings but there is a high risk of thunderstorms in the afternoons and nights.

In the summertime, warm weather facilitates the chances of lighting in the Rocky Mountains. And as we know, thunderstorms are very dangerous if we are caught up there in the mountains.

Experts on climate affirm that every year, almost the area is affected with 25 million lightning strikes that have caused injuries to explores and hikers. So if you are visiting this area during the summer, you better organize your activities early in the morning until two or three in the afternoon.

Throughout the Napoleonic Wars, American diplomatic neutrality was put to the test (1803-1815). In order to harm each other's economies, the at-war nations of Britain and France both imposed trade restrictions. Additionally, these restrictions hampered American trade and put the nation's neutrality in jeopardy.

Why did the French and English go to war in the 1800s?

In their struggle for dominance in Europe, Great Britain and France used force against smaller, less powerful nations. During the Napoleonic era, the United States made an effort to maintain its neutrality, but it ultimately became involved in the wars in Europe, sparking the War of 1812 with Great Britain.

The British started to impose restrictions on American shipping, though, in 1805. They didn't want Americans to feed and supply their enemies. The British made the decision to erect a partial blockade in response to the United States threats to take action. Only a few American ships could now transport supplies to Europe as a result.
