Five business students, with a University of Phoenix learning team, noticed the recent increases of regular unleaded gasoline prices. The students hypothesized the gas prices consumed from corporate stations are not the same price as if purchased from a generic station in a grocery store parking lot, with a confidence interval of 90%. The research team decided to limit the current research to the Houston, Texas area. The students would take a sample, in the natural environment, to include five corporate gas stations and five different grocery stores around Houston.
Retailers, such as Wal-Mart, Kroger, and Randall 's (big box retailers), are capturing a growing percentage of the market share of gasoline sales from conventional convenience formats, and additionally, have helped to reduce the mean price of gasoline through lower profit margins and competitive practices. Research indicates since the inception of big box retailers, during mid-1980 into the fuel sales market, overall corporate convenience-store fuel sales have decreased by an average of 13% on a national scale (American Independent Business Alliance, 2005). This decrease is estimated to rise by as much as 16% by 2007 and is likely to continue as retail giants such as Wal-Mart and Kroger vie for fuel sales as an incentive to lure more customers into their stores. At the pump advertising, discount cards, and free-gas with in-store purchases are just a few incentives that big box retailers are offering consumers to keep him or her in the stores and these tactics seem to be paying off. Typical profit margins, for big box retailers, in gasoline average about 8% for each gallon of gas sold and are a far reach from corporate gasoline outlets before big box retailers entered the market. Markups of over 20% were once the norm for convenience outlets on gasoline, but profit margins have narrowed drastically as convenience stores try to compete with an ever growing threat

    The results exhibited that the interaction of early child adversity severity and those stressful life events involved predicted an occurrence in a manner consistent with the research hypothesis for both the men and the women. Therefore, we reject the null hypothesis. There were some limitations to this research issue and the hypothesis testing procedure. The sample size and the number of past episodes were determined retrospectively, mainly through self-report. But, another thought to keep in mind is the individuals who experienced early child adversity had a significantly younger age of bipolar onset. Concerning this conclusion, it would be of great importance for the suggestion for further studies of stress mechanisms in bipolar disorder and of treatments designed to intervene early among those at risk. I would propose when and if the conditions of bipolar disorder are identified, an effective treatment plan needs to be implemented. This approach would be of great benefit for the patient 's health, wellbeing, and longevity. Studies speak for themselves regarding childhood adversity being prevalent and having pervasive and long term impacts on mental and physical…

    In the Harvard Business Review article "Market Lunacy," Lisa Burrell describes how researchers Ilia Dichev and Troy Janes asked the question whether the common belief that the moon changes moods and causes depression may actually be accurate or is it a myth. They believe that most studies have focused on extreme cases so they decided to focus on stock exchanges with the assumption that something that involves millions of people around the world participating in it every day should indicate any deviation from the norm. The researchers were looking at the hypothesis that depressed people affected by the moon will cause a drop in stock prices. Dichev and Janes looked to prove or disprove the theory of the moon affecting behavior, so they studied the daily median stock price profits of 25 stock exchanges over the last thirty years. In their findings, they learned that there is indeed a drop in stock price profits on the day of a full moon versus the day of a new moon.…

    Inside statistics, it has to be understood what hypothesis testing is to find and verify research to be studied. Hypothesis testing is a form of research that is used to show how a certain issue will end or how the researcher(s) think the issue will end in the environment that it is situated. The testing will show that even though an answer may form, it does not prove the answer is correct secondary to the fact that there can me many factors that could change the outcome; this is where researchers can use probability rates of five or one percent. In understanding hypothesis testing, it must be known what the difference between null and research hypothesis means. A null hypothesis attempts to show that there is no variation between variables or that a single variable is actually no different from zero. A null hypothesis is what the researcher attempts to disprove, reject, or nullify. The research hypothesis is the specific testable predictions made about the independent and dependent variables inside the study. With the research hypothesis, it matches what the researcher(s) is attempting to prove true inside the problem or issue.…

    Homelessness is an ever growing problem that the numbers seem to increase in severity in the larger cities. Chicago, Illinois has numbers that exceed more than 93,000 individuals that are homeless and out of those there is close to 20,000 that also suffer with a mental illness. In addressing the link between mental illness and homelessness it is clear that the numbers are large due to lack of medical care and the de-institutionalization from the 1960’s. In an attempt to prove this it is going to be discussed in how one that has a mental illness that is untreated will also have a higher increase of homelessness.…

    Hypothesis testing is a method of making decisions using data from scientific study. In statistics, a result is called statistically significant if it has been predicted as unlikely to have occurred by chance alone, according to pre-determined threshold probability, the significance level. Statistical hypothesis tests define a procedure that controls (fixes) the probability of incorrectly deciding that a default position (null hypothesis) is incorrect based on how likely it would be for a set of observations to occur if the null hypothesis were true. The null hypothesis, H0, is a statistical proposition stating that there is no significant difference between a hypothesized value of a population parameter and its value estimated from a sample drawn from that population. Hypothesis testing is very counteractive for nurses and their research. A perfect example for hypothesis test is testing whether or not men or women have the most nightmares.…
