Chi-square distribution

P(x<0) P(x>1) P(x?4) P(4 5. Calculate the mean and standard deviation (by hand) for the MINITAB created binomial distribution with the probability of a success being ½. Either show work or explain how your answer was calculated. Mean = np, Standard Deviation = Mean: Standard deviation: 6. Calculate the mean and standard deviation (by hand) for the MINITAB created binomial distribution with the probability of a success being ¼ and compare to the results from question 5. Mean = np,…

be the case. Poverty rates can either increase or decrease depending on rising income inequality, income growth, and changes in the educational levels, family structure, and prejudice terms. The United States has one of the most unequal income distributions in the developed world; “even after taxes and social-welfare policies are taken into account” (Drew Desilver). Income is one of the top ways people measure “economic inequality”. The United States is ranked tenth in income inequality compared…

Analysis of Galvanized Nails, Quality Control, and Green Chemistry Introduction: In this lab, we handled acidic chemicals that needed to be disposed of upon completion of the lab. We disposed of these chemicals according to safety policies and green chemistry policies. Green Chemistry is the practice of chemistry in an environmentally safe way to prevent pollution. We used green chemistry to minimize the amount of waste we were to be creating. We ended up creating waste from degalvanizing…

The Income and Wealth Inequality of America As a capitalist nation, the United State of America is facing a serious problem, which is the inequality of wealth and income. In pace with the growth of the economy, the rich people are getting richer and the poor people are getting poorer. The gap between the rich and poor is widening unprecedentedly fast. Why is that happening? Most of the rich people believe the strategy of trickle down economic. When their corporations earn money, and they can…

Boldly stated within a viral video titled "Wealth Inequality in America" is that "[most people] certainly don 't have to go as far as Socialism to find something that is fair for hardworking Americans," a statement that colorfully highlights one of the largest issues in America today: the wealth gap. Using statistics, the creator of the video proves that the saying “While the rich get richer, the poor get poorer” is true; as the rich are given an excess of opportunities to gain more money, the…

factor discussed was the discovery that computations can be utilized to measure observational error, by and astronomer, Lambert Adolphe Quetelet. This discovery led to the development of the normal distribution curve utilized today (Cowles & Davis, 2016). Following the development of the normal distribution curve, a measure of variability known as probable error was discovered (Cowles & Davis, 2016). This discovery was the second factor mentioned by Cowles and Davis (2016) that contributed to…

The Relation of Work, Wealth, and Interdependence Everyone knows that the harder one works the wealthier they will be. The logic makes sense, people who are lazy and do little work won’t do their job, and therefore won’t become wealthy. When a person works hard it makes sense that they will earn a lot of money. This means that work and wealth are directly related, as one increases so does the other. Even though it is commonly believed that wealth is acquired by hard work there are some people…

4. Empirical results In this section we discuss the empirical results of the VAR model analysis described in the previous section. In subsection 4.1 we analyse significance of coefficients in the model and apply Granger Causality test. In subsection 4.2 we present the results of impulse response functions analysis and variance decomposition. Afterwards, we turn to subsection 4.3 to test reliability of the VAR model. 4.1 Testing for significance and Granger-causality According to Wald test…

When conducting a hypothesis test for the difference between two means it’s essentially called a two sample t-test. According to Dr. Mirabella (2011, p. 5-2) states that, “In each case you can conduct a t-test for independent means to determine if a significant difference exists.” Furthermore, we’re conducting this test to see if there is an overlapping or if there is clearly a difference among the GPAs for men and women. In our case we are comparing the GPAs for a sample of men and a sample…
