Creating and Argument: The Electoral College

 100% Plagiarism Free!!!

This week we learned about the presidency, the powers of the presidency, and the unique way our president is elected via the Electoral College. In this assignment you will be guided in creating a complete argument regarding whether or not you think the Electoral College should be kept or eliminated.

This activity will be useful practice in how to create and present and thoughtful argument. The ability to create and communicate a thoughtful argument will help you out in future studies and in any career.

Follow these steps to create an argument in the form of an essay:

Step 1

In one or two very clear sentences state whether or not you think the Electoral College should be kept or eliminated. This is called writing a thesis statement.

Step 2

In three paragraphs describing three (3) arguments that support your position regarding the Electoral College. Give each argument one paragraph. Do not just list three arguments in support of your position regarding the Electoral College. You must tell the reader why each of your three arguments supports your position on the Electoral College.

Step 3

In three paragraphs describe three (3) arguments that go against your position regarding the Electoral College. This is called addressing counterarguments. Give each counterargument one paragraph. Describe the counterargument and then tell the reader of your essay why that counterargument should be dismissed.

Step 4

Write one paragraph concluding your essay. Restate your initial position on the Electoral College. And review the one or two arguments that you found to be the most compelling in support of your position.

Step 5

Write a reference list. In any good argument you will present your ideas but then include evidence from credible external sources to support your ideas. Always include a reference list.

In outline form your paper should look like this.

1.  Introduction: Thesis statement of your position regarding the Electoral College.

2.  Three arguments supporting your position.

a.  Describe argument 1 and why it supports your position.

b.  Describe argument 2 and why it supports your position.

c.  Describe argument 3 and why it supports your position.

3.  Three counter arguments opposing your position.

a.  Describe counter argument 1 and why it is not sufficient.

b.  Describe counter argument 2 and why it is not sufficient.

c.  Describe counter argument 3 and why it is not sufficient.

4.  Conclusion paragraph.

Please note: APA formatting and citations rules apply to this and all essays in this course.

As with all weekly written assignments, submit your work as an attached file. Double-space your paper and use 12 point Times New Roman as your font.

Children in the United States account directly for $36 billion in sales annually. When their indirect influence over product decisions from stereos to vacations is considered, the total economic spending affected by children in the United States is $2

Question 9.48

Children in the United States account directly for

$36 billion in sales annually. When their indirect influence

over product decisions from stereos to vacations is considered,

the total economic spending affected by children in the

United States is $290 billion. It is estimated that by age 10.

a child makes an average of more than five trips a week to a

store (data extracted from M. E. Goldberg, G. 1. Gorn, L. A.

Peracchio, and G. Bamossy, “Understanding Materialism

Among Youth,” Journal of ConSlimer Psychology, 2003.

13(3), pp. 278-288). Suppose that you want to prove that

children in your city average more than five trips a week to

a store. Let fL represent the population mean number of

times children in your city make trips to a store.

a. State the null and alternative hypotheses.

b. Explain the meaning of the Type I and Type II errors in

the context of this scenario.

c. Suppose that you carry out a similar study in the city in

which you live. You take a sample of ) 00 children and find that the mean number of trips to the store is 5.47 and the sample SD of the number of trips to store is 1.6. At the 0.01 level of significance, is there evidence that the population mean number of trips to the store is greater than 5 per week?

 

d) Interpret the meaning of the p- value in (c )

Proofing Summary:

 

I’m Stacey, your composition tutor for the Writing Center. I have reviewed your submission and have several

 

suggestions that will help you revise. Please feel free to contact us through a live chat session with any follow-up

 

questions or for any clarification.

 

Below, you will find a revision plan along with margin comments within your paper. Use my suggestions as a starting

 

point for the revision process. Also, please note that I have not edited or proofread the entire draft for minor errors, but

 

rather, focused on overall concerns such as idea development. For a complete look at your grammar and punctuation,

 

please use the Grammarly software available under “Writing Center” in your classroom.

 

For your revisions, I suggest focusing on:

 

1. Prompt

 

Keep in mind that your paper is a literary analysis. A literary analysis

 

involves some summarization , but you should not write a report. A

 

literary analysis focuses on how plot/structure, character, setting, and

 

many other techniques are used by the author to create meaning. For more

 

help concerning the prompt, please see below:

 

Guiding Questions:

 

1. How do we know that the protagonist is impoverished? Is she content with her class? Why or why not?

 

2. How do we know that she is African-American? How does her alienation due to her race also connect with her education?

 

3. The protagonist’s daughter, Dee, who has embraced her African roots, accuses her mother of not understanding her

 

heritage. Why? What is the situational irony at the end of the story?

 

2. Thesis Statement

 

Make sure that you have a strong thesis statement at the end of your introduction. Your thesis statement should 1)

 

contain your debatable claim about the work, and 2) list the specific points you will develop to support your claim. See

 

the example below.

 

In “The Masque of the Red Death,” Poe uses the symbolism of the stranger, the clock, and the seventh room to develop

 

the theme of death

 

Based on the sample thesis, the first supporting paragraph will be about how death is symbolized by the stranger. The

 

second supporting paragraph will be about how death is symbolized by the clock. The third supporting paragraph will be

 

about how death is symbolized by the seventh room.

Everyday Use

 

Prompt: In some stories, characters come into conflict with the culture in which they live. Often, a character feels alienated in his/her community or society due to race, gender, class or ethnic background. The texts below all contain a character who is ‘outcast’ or otherwise disconnected from society in some way, reflecting important ideas about both the character and the surrounding society’s assumptions, morality, and values. Choose a text and consider the questions below as you critically read the text. Then, craft a working thesis that suggests how this alienation is expressed in the text and why it is significant.

 

Culture is the way of life of a group of people. These people have similar characteristics such as a common ancestry, geographical location or even religious beliefs. Culture governs all facets of our lives. It determines our worldview on various issues as well as our beliefs, attitudes and moral compass. Culture, therefore, bestows us our identity, and it is important that one retains their culture. Culture is an indispensable part of the human existence. It shapes our lives as well as our value systems and gives us our sense of identity and belonging (See, 1998). Alienation from our cultures makes us lose our sense of identity and belonging, as seen in the reading Everyday Use. As such, it is crucial that we uphold and retain our culture so as to preserve who we are.

Remember that short story titles are in quotation marks.

 

 

 

Remember that your thesis

 

statements should state a claim

 

(your opinion of the work) and

 

the reasons you feel your claim

 

is true.

 

 

 

 

 

Alienation causes us to lose the sense of our heritage and by doing so, makes us lose our identity. Dee is alienated from her heritage. She has sought to change her name from Dee to Wangero in a bid to honor her African roots (Walker & Christian, 1994). However, by doing so, she distances herself from the heritage of her family. The name Dee has been passed down for generations in her family, honoring the line of strong women that came before her and bestows her her identity (Gale, 2016). She believes that taking on the name Wangero makes her shun the sign of racism and abuse (Walker & Christian, 1994). However, she does not understand that it links her to the strong women that came before her. She is confused about her heritage and does not even understand the new culture that she is trying to adopt. The name Wangero is supposed to be Wangari, but she is not aware (Gale, 2016). In her search for emancipation and connection to her original culture, she loses her sense of heritage and by doing so loses her true identity.

 

Alienation causes us to lose one’s connection with the family. Culture helps us keep our connection with the family. Even with the worldly influences such as education, one’s culture help’s them to interact and feel the bond of family with members of their kin. Alienation from one’s culture causes a rift in one’s family relationships and leaves without the bond of family love. Dee is seen to be distant from her family. Maggie seems nervous and fidgety before and when Dee comes to the home. Mama has to hold her to prevent her from running into the house once Dee arrives (Walker & Christian, 1994). Dee had never appreciated her home and the way of life of her mother and sister. She causes discord once she asks for the quilts and tells them that they do not understand their heritage because they plan to use the quilts rather than preserving them. She urges Maggie to leave the simple life she lives as it is a new age for Black people (Walker & Christian, 1994). All this is because she is alienated from her culture. Her new ways intimidate her mother and sister, and her lack of appreciation of the quilts makes it an issue when she asks for them. Her education and materialistic nature do not allow her to understand the contentedness of her mother and sister in their simple life (Gale, 2016). This makes her not relate well with her family. Alienation has clearly affected the family ties in this family.

 

Is this a proper noun?

 

Do you need to show ownership here?

 

 

 

Alienation can also cause one to lose their understanding of their history, which is necessary for self-discovery. One’s history is essential to their life. It allows us to appreciate where we have come from and the achievements of those before us. It also impacts values that guide us on the road to self-discovery and self-improvement. Dee does not understand the history of her culture nor does she understand the history of her African roots. She does not appreciate that the quilts are living history that connects the user with the previous generations of strong women from the family (Walker & Christian, 1994). The quilts show the resilience of the family to face all obstacles and the achievements of the previous generations. By using them, one connects with these generations. Her African roots are also unclear to her, as is seen by her using the name Wangero, which is in fact supposed to be Wangari (Gale, 2016). Her alienation has made her unable to understand her heritage, and this denies her connection with her ancestors. She, therefore, remains in a state of limbo, unable to achieve self-discovery.

 

In conclusion, one’s culture is vital to their life. It allows one to know who they are and guides one’s life by offering essential value systems that will help them improve the quality of their lives in the future. Alienation causes the individual to lose one’s sense of heritage and consequently lose their identity. It also causes one to lose their connection with their family as well as lose their understanding of their history which is vital to the process of self-discovery. It is, therefore, paramount that one retains their culture. Culture is an indispensable part of the human existence. It shapes our lives as well as our value systems and gives us our sense of identity and belonging (See, 1998). Alienation from our cultures makes us lose our sense of identity and belonging, as seen in the reading Everyday Use. As such, it is crucial that we uphold and retain our culture so as to preserve who we are.

 

Good job on your conclusion. You do a good job of restating your thesis, summarizing your main points, and wrapping up

 

your paper.

Statistics

PROBLEM 1
Kathleen Vohs of the University of Minnesota and her coworkers carried out several randomized comparative experiments on the effects of thinking about money. Here’s part of one such experiment. Ask student subject to unscramble 30 sets of five words to make a meaningful phrase from four of the five words. The control group unscrambled phrases like “cold it desk outside is” into “it is cold outside.” The treatment group unscrambled phrases that lead to thinking about money, turning “high salary desk paying” into “a high-paying salary.” Then each subject worked a hard puzzle, knowing that they could ask for help. Here are the times in seconds until subjects asked for help:

 

Treatment group:
609 444 242 198 174 55 251 466 443
531 135 241 476 482 362 69 160

 

Control group:
118 272 412 290 140 104 55 189 126
400 91 63 87 142 141 373 156

 

The researcher suspected that money is connected with self-sufficiency, so that the treatment group would ask for help less quickly on the average. Do the data support this idea? Use a 5% level of significance.

 

EXPECTATIONS
– Draw graphs and charts when appropriate and necessary to demonstrate your reasoning! Label all graphs and charts!
– Display formulas. Write complete sentences to summarize your conclusions.
– If use any table values, clearly state which tables you used (e.g. Table A-2, etc.).
-Attach excel output when appropriate or necessary (e.g. a scatterplot, etc.)

HYPOTHESIS TESTING QUESTIONS
Your work for all statistical hypothesis testing questions should include the following:
1. Established Ho and Ha.
2. Summary statistics (either computed or given in the problem)
3. The name of the test (e.g. 2sampleTtest or T-test about correlation, etc.)
4. A formula to compute a test statistic (e.g. 1Prop-Z test statistic, etc.)
5. A p-value of the test and/or a critical value from a statistical table.
6. Clearly state the decision rule you use the reach a conclusion. (You may have to sketch a graph to show rejection regions.) Do you “Reject Ho” or do you “Fail to Reject Ho”?
7. State your conclusion in plain language. Use complete sentences.
