Question How does changing the size of the airplane affect how far the airplane goes. Hypothesis If we change the size of the airplane then the paper airplane will go further. Materials Paper, graph paper, meter stick, a pencil, Procedure: 1.I will build two identical paper airplanes. One will be my control airplane that is smaller and the other will be my test airplane the one that is bigger. 2.I will throw my control plane 10 times and I will use a meter stick to measure the distance of…

Inequality is something everyone faces in America, whether beneficial or detrimental towards individual lifestyles, it has become the one thing we cannot escape. Those in the upper class who benefit from the expansive wage gap are quick to say how such a great inequality does not truly exists, or how with hard work and perseverance anyone could be successful and rich. However in a time where the wage gap is greater than ever and the socio-economic divide is expanding, we can no longer ignore the…

In “For Richer, For Poorer”, The Economist (2012) is about the growing income inequality, which is one of the global biggest social, economic and political challenges, It also examines how this growing inequalities create a wider income gap between rich and poor and suggests some solutions to resolve it. The article mentions, to give the income inequality background that the concern of inequality existed long time ago and became better with the time in the way that the live standards of the poor…

First of all, the public is polarized politically based on economic inequality. The economic growth of the U.S. economy has improved the financial position of those of higher incomes, while lower income citizens stayed the same. This unequal distribution of growth is recognized as income inequality. Those at the top could utilize resources to prevent the redistribution of America's wealth, while those at the bottom would do the opposite. Polarization amongst the politicians are related to the…

The gap between rich and power is widening: there is a divergence of income due to economic downfal. An American’s economist, author Robbert Reich, wrote “Why the Rich Are Getting Richer and the Poor, Poor” in the 1990's, and he argues that America has a huge growing economic gap, it is the growing gap between the rich and the poor. Reich uses a metaphor to support his essay on “all Americans used to be in roughly the same economic boat,” he also explains that how the economy is falling down,…

Income inequality is the uneven distribution of assets among a population. In India, income inequality has been rapidly increasing over the pass years. Due to the expeditious growth of population, the discipline of the society begins to collapse, resulting in a rise of many inequalities in health, education and gender. In India, the top 1% holds nearly half of the country’s wealth and the rest of India owns only the remaining quarter. This unequal distribution of wealth is caused by the failure…

Discussion: The distribution of each graph is quite comparable as they have similar means and standard deviation, where the preferred hand has a mean of 16.33 and a standard deviation of 2.842 whilst the non-preferred hand has a mean of 17.2 and standard deviation of 2.848. The normal distribution graph of each can be seen below: Preferred Hand vs. Non-preferred Hand: The graphs and boxplots (Figures 1.3- 1.6) seen previously in the results indicate that the two results did not have a normal…

Smart Grid Technologies: Communication Technologies and Standards Smart Grid History As soon as electrical distribution grids came into being the need for metering arose. The initial devices were used for metering consumption, however modern smart grid technology uses two way metering and can switch appliances on or off according to demand and off peak tariffs. Over the last one hundred years many obstacles to smart grid technology have been overcome. The earliest attempt at smart grid was…

In Leonhardt’s essay “Inequality Has Been Going On Forever…But That Doesn’t Mean It’s Inevitable” Leonhardt explains how the middle class is suffering in a prosperous nation.

Leonhardt’s concern is the rapid pace in rising inequality, as the wealthy are affluent in capital gains, taxes, and…

The third problem was chosen to demonstrate the use of a method described in Rand Wilcox’s book [4] and implemented as a Minitab® macro in the diskette accompanying the book [5]. In class discussions lead to my interest in Yuen’s test of trimmed means which is appropriate for situations when there is evidence of non-normality and heteroscedasticity [4]. If there is no violation of normality but there’s is heteroscedasticity, the Yuen’s test without trimming, which is actually the classical…
