3a. Figure 7.2 depicts a normal sampling distribution, which is being used to calculate a difference of proportions test of significance. The image shows the calculation of a confidence interval that is 1.96 times the standard error, i.e. 95 percent confidence. It also shows how the application of this confidence interval about the mean creates two legs outside of the mean, which, in this case, each represent 2.5 percent confidence respectively. 3b. Percentage of Republicans in 1984: 44.22% Percentage of Republicans in 1992: 41.86% = = -0.99 to 5.71 3c. Based on this equation, we can conclude that we cannot eliminate the possibility that there was no significant change in the number of Republicans from 1984 to 1992. This is because the 95% confidence interval includes within it the result we would expect to see if the null hypothesis were true, i.e. if there was no difference between the number of Republicans in 1984 and 1992. In this case, the null hypothesis is that - = 0 and 0 falls within the range of -0.99 to 5.71. Therefore, there is a greater than 5% chance that the difference is 0 and thus the null hypothesis cannot be eliminated. 4a. According to the stated hypothesis, Bush would have received half of Perot’s voters (129), bringing Bush’s number of voters from 477 to 606. However, the other half of Perot’s voters would not have voted, thus lowering the total percentage of voters (i.e. the denominator) from 1335 to
12. _____ For a given population, confidence intervals constructed from larger samples tend to be narrower than those constructed from smaller samples. Which statement below best describes why this is true? (A) The variability of the sample mean is less for larger samples. (B) The z-value for larger samples tends to be more accurate. (C) The population variance is larger for large populations. (D) As the sample size increases, the z-value (or t-value) becomes smaller. A machine dispenses potato chips into bags that are advertised as containing one pound of product. To be on the safe side, the machine is supposed to be calibrated to dispense 16.07 ounces per bag, and from long time observation, the distribution of the fill-weights is known to be approximately normal and the process is known to have a standard deviation of 0.15 ounces.
A random sample over the course of a few weeks produces 91 surveys or customer complaint cards. The observations produced a mean of x= 26.1 and a standard deviation to s= 2.8. Since the sample size is large the standard formula will be used. The equation will be 26.1 + and – 1.960 2.8 / the square root of 91. Once the calculations are done we can determine the calculations will be 26.1 + and – 0.58. Thus the 95% confidence level for u will be 25.52 and

The survey 's margin of error was 3%. Construct a confidence interval for the proportion of left-handed golfers.
Taking Poverty 101 class is a way to learn about poverty and what causes it (Beegle 342-343). In the article All Kids Should Take 'Poverty 101,' Beegle explained that in order to help the poor, we first need to be able to sympathize and understand their situations (342). Poverty 101 class will help us to do so because through this class, we will learn the real meaning of poverty, what causes it, and the attitudes that Americans have toward poverty and people who are in it. Moreover, we will get exposed to different types of poverty, such as generational poverty, working-class poverty, immigrant poverty, and situational poverty.
Atlanta is the capital and largest city in Georgia, with a population of 472,522, and one of the fastest growing major cities in the United States.1 Originally, known as a railroad settlement, it was founded in 1837 as the end of the Western & Atlantic railroad line (the name changed from Marthasville to Terminus, to finally Atlanta, the feminine of Atlantic).16 In 1861, became one of the 11 states seceding from the Union over the issue of slavery.17 It was also the home front during the Civil War and a major producer of war materials, and the regional transportation and distribution center.17 Post-war, due to railroads, Atlanta continued to economically grow and diversify, along with its population.17 A large number of African-Americans were

The goal of TRPO is to help explain the link between race and poverty, understand which barriers to success are personal and which are institutional, discuss the ways in which educational advantages make a difference in life, and recommend changes to increase equitable access to any race. This non-governmental organization has been working towards the elimination of extreme poverty since its founding. Work, including donating to those who are having trouble economically because of their race. This is an organization where you can donate any amount of money to help those who are struggling. The money will go to children who are affected by their parents income. The money will then help those children get a better education and better live in
In response to the Great Depression, the government very slowly began, although without success at first, to develop policies that would help to alleviate the problem of poverty. The first universal social welfare program they came up with was the Family Allowance program, which was introduced by the federal government in 1944. The small unemployment insurance program, introduced during World War II, was expanded after the war. These were the foundations of Canada’s social security system or welfare state. The problem of poverty was not solved, however, and relative poverty (meaning wide gaps between low-income earners and others) persisted.
That means 36 percent had not bothered to show up. Popular votes would be highly influenced by the 36 percent. “The precautions which have been so happily concerted in the system under consideration, promise an effectual security against this mischief.” said Alexander Hamilton. He believes the Electoral college protects us. How the public views candidates can be altered. Although it seems the people have no effect on the presidency, they do. Smaller state feel that on a daily basis, especially because of their population.
f) Find a 95% confidence interval for the difference between these proportions. From this interval, can we conclude that there is a significant difference in the proportions at the 5% level of significance?
The months following the dropping out of the election, Ross Perot had clearly benefited Clinton; this ultimately took away votes from Bush. On October 1st 1992 nearly a month from election day Perot had re-entered the race, a poll had taken place mid-October which showed Clinton had dropped to 48%, Bush 35% and Perot 8%. At the end of October, the polls had shown Clinton at 44%, Bush at 34% and Perot had jumped to 19% in less than a month. When these numbers were figured, the press released a statement saying, “Ross Perot's surge in the polls is drawing somewhat more support from Bill Clinton than from George Bush, and the third party candidate seems poised to make more gains that might further narrow Bill Clinton's nationwide margin.” (Voting
This paper provides an economical framework for why poverty is so prevalent throughout the United States (U.S.) and what can be done from an economic standpoint to help eradicate it. The paper is aimed to tackle the question of its inevitability by the Author Douglas Massey who wrote about the rising rate and concentration of poverty. While simultaneously breaking down the barriers to economic growth due to a structural poverty that has grown persistently with time. It will also addresses how the government can collaborate with the community in hopes to combat poverty through means of income and wealth distribution. The ideal outcome will be achieved by generating opportunities for the poor through growth promoting polices, distributing the
Conclusion : Reject the null hypothesis. The sample provide enough evidence to support the claim that mean is significantly different from 12 .
Poverty is “the state or condition of having little or no money, goods, or means of support; condition of being poor” (Dictionary.com, 2017). Based off this definition poverty is a condition that can cause a cascade of cause and effect actions that is detrimental to families and individuals both physically and mentally. Haan, Kaplan, & Camacho (2017) completed a study on the correlation between social and economic status and health in adults in Oakland, CA. They found that the lower the socioeconomic class the higher incidents of diseases and deaths related to chronic diseases (p.1161-1162). Just being without money or little money was not the only indication of health indication, a person living in an area with higher poverty issues
A social problem, is “a general factor that effects and damages society”. It can be used to describe an issue or a problem within a certain group of people or an area in the world. Examples of contemporary social problems today include anti-social behaviour, drug abuse, and sexual abuse. Poverty is an example of a social problem that exists all over the world, and to different extents. In the UK, poverty has effected at least a third of the population, as shown by the Office of National Statistics, providing evidence that it is a massive social problem in the country. Tameside has a big poverty problem. 1 in 4 children in Tameside are born into poverty, and workers in Tameside earn significantly less than other workers in the rest of the North-West area. In addition, Tameside has the largest proportion of people claiming unemployment benefits compared to the rest of the North West of England.
