Null hypothesis

To do this experiment you will need two subjects that have different arm lengths. In this experiment Subject 1 had an arm length of .81 meters and Subject 2 had an arm length of .77 meters. It is crucial that the subjects have different arm lengths because if they don’t your results will be invalid. The first step in this experiment is to set up the camera using the tripod and insert an SD card. Next, position the camera perpendicular to the sagittal plane along the x-axis in regards to the…

¥ For how many students do you have Verbal Aggressiveness scores? We have Verbal Aggressiveness scores for 59 students. ¥ What is the mean for the entire sample? The mean for the entire sample is 44.0169. ¥ How do you interpret the mean score? When we interpret the mean score, we should look at the minimum and the maximum scores, so we can see the mean are close to each one. In verbal aggressiveness, the minimum is 26 and the maximum is 65, which indicates that the mean around the middle of…

In the experiment conducted by W. Scott Terry, they set out to find out whether the placement of a commercial in a set of commercials would impact the ability for a person to recall the specific commercials and specific details from said commercials. They wanted to know whether there would be primacy or recency effect when recalling information. The serial position for the capability to recall the commercials under naturalistic conditions was an important factor for how people were able to…

Fooled by Randomness Critical Review This book was hard for me to grasp at first, but it became very interesting after a few chapters. Taleb has changed the way I look at business and the world of financial markets. Fooled by Randomness looks at randomness in a wide-ranging setting and it also looks at all the ways in which it twists our thinking. It also emphases more precisely on the markets and trading. It still ranges into other areas of life and overall philosophy, but Taleb delivers more…

Have you ever worried about aliens invading? What about being abducted? What is our plan for any extraterrestrial event coming to earth, either in peace or harm, and making contact with us humans (Murphy)? Aliens are known to have a multitude of different characteristics and features. There are many examples and forms of proof that extraterrestrials have an existence. Multiple sightings and stories have been proven hoaxes. Popularization of aliens through media greatly accounts for widespread…

Clearly, randomization is crucial to eliminate certain bias and have an accurate trial. 6. Explain how the intervention(s) in the treatment arm differed from how participants in the control arm were treated. In other words, what is the trial testing? Participants in the treatment arm were given 12.5 milligram Zinc Sulfate, whereas the participants in the control arm were given a placebo. The trial is testing whether Zinc Sulfate is beneficial to children who have Malaria or not. 7. Was the…

The foot is a complex conglomerate of joints, ligaments, and muscles. It is through the interplay of these structures which gives humans the ability to walk and perform different functional tasks in a bipedal stance. The foot is vulnerable to a significant amount of stress during the daily grind. Hence, these repetitive stress at times can be the antecedent to certain foot pathology. This theory on repetitive stress is currently one of the accepted causes of a painful foot condition known as…

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 (Table 5) the hypothesis of zero coefficient before oil price variable in GDP equation is not rejected in all analysed countries except Russia. This means that Russia is the only country where oil prices effect real economic activity directly. The fact…

Cumulative prospect theory ( cpt) Introduction Cumulative prospect theory (CPT) is a model for descriptive decisions under risk and crisis which was introduced by Amos Tversky and Daniel Kahneman in 1992 (Tversky, Kahneman, 1992). It is a further development and variant of prospect theory. The difference between this version and the original version of prospect theory is that weighting is applied to the cumulative probability distribution function, as in rank-dependent expected utility theory…

Introduction: Based on preliminary research, the hypothesis of the present study was that at temperatures higher or lower than 40 degrees Celsius fermentation is inhibited. Alcoholic fermentation is used in food production such as brewing, winemaking, and baking (Campbell). Thus optimizing fermentation and understanding the effect of various environmental factors can have important economic and social benefits. The production of CO2 is being assessed to show the rate of fermentation at certain…
