Hypothesis. Conditional on preferring the outcome from lying over the outcome from truth-telling‚ a person is sensitive to neither her own [monetary] gain from lying‚ nor how much [monetary] harm she causes the other side. Notice that aside from the preface of “preferring the outcome from lying”‚ the rest of the Hypothesis seems quite at odds with Gneezy’s Result. The reconciliation is that a significant fraction of Gneezy’s subjects prefer the outcome from lying to truth-telling in some experimental

Observations of Chemical Changes Purpose: To observe some properties of chemical reactions and associate them with everyday household cleaning products. Procedure: In order to complete this experiment‚ I had to set up and organize my lab table. I used my 24-well plate‚ my 96-well plate‚ and the first experiment bag which included all of the necessary chemicals. I also had to gather 3 household cleaning products and a pipet in order to test them as well. The procedure involved was putting 2 drops of

standard deviation is 12. Using the five steps of hypothesis testing and the 5% significance level (i.e. alpha = .05)‚ does showing the film change students’ attitudes towards the chronically mentally ill? What does it mean to set alpha at .05? Alpha means making a Type I error same as significance level. When the alpha is at .05 it means that the researcher doesn’t want to take a big risk therefore sets the alpha to .05. By doing this it will make it hard for hypothesis testing process to reject

GUNS‚ GERMS‚ AND STEEL ESSAY Jared Diamond’s novel‚ Guns‚ Germs‚ and Steel is a speculation about how and why the Europeans ended up being the main power in earlier times and conquered so much of the world. Diamond wonders how the Europeans could have so much power and advanced technology while the rest of the world was still hunting and gathering. Although Diamond is not the first to speculate on this complicated subject‚ his answer is revolutionary. People have attributed Europe’s overwhelming

that the duckweed grows faster in the NP solution‚ rather than the creek water they do indeed have relatively the same mean. Overall our results supports our hypothesis. This also makes us question what kinds of factors are affecting the creek water to kill off the duckweed. Duckweed also is known to stop the growth of algae‚ but in our experiment we ended up having algae grow in some of the wells filled with creek water. We feel as though the creek water might have had some chemicals in it through runoff

Stock Evaluation Project - Steel Industry Industry Analysis Steel is a part of metals and mining industry which is highly cyclical in nature‚ and when the economy at large suffers‚ this industry suffers with it. The most recent five years have been a struggle for this particular industry along with uncertain economic indicators‚ and steel companies’ stocks have trended downwards. The metals and mining industry is comprised of companies that engage in exploration‚ mine development‚ and ore mining

A one population test using the One Factor ANOVA test and a five-step hypothesis test can be used to determine if gas prices are equally high in many different states. The samples used to test the hypothesis come from data collected from 30 randomly selected gas stations in six different cities. The hypothesis test and some solutions to consider may have an effect on direct and indirect stakeholders and is very important

Question 1: State the null hypothesis and alternative hypothesis ONLY i) One of the major Malaysia tire makers wishes to review its warranty for their rainmaker tire. The warranty is for 40‚000 kilometers. The tire company believes that the tire actually lasts more than 40‚000 kilometers. A sample 49 tires revealed that the mean number of kilometers is 45‚000 kilometers with a standard deviation of 15‚000 kilometers. What is the null hypothesis and alternative hypothesis? ii) It is claimed that

known amounts of reactants‚ theoretical amounts of product can be calculated in a chemical process. These calculated products are determined using the limiting reagent‚ (the substance that runs out first which stops the reaction) and are called the theoretical yield. The theoretical yield is the amount of product that should be acquired during the experiment if all aspects go perfectly. However‚ due to experimental errors‚ very few labs do so. These results are called actual yield. The percent ratio

The dopamine hypothesis evolved from animal studies conducted in the 1960s showing that neuroleptic drugs blocked dopamine receptors in the brain. An article by van Rossum published in 1966 is often cited as the first expression of the dopamine theory of schizophrenia‚ but in fact‚ the article concerned only the mode of action of neuroleptic drugs. It stated: “The hypothesis is therefore put forward that dopamine receptor blockade is an important factor in themode of action of neuroleptic drugs
