Statistic

treatment of program A. The P-value for this estimate is <0.0001. This provides strong evidence against the null hypothesis, that there is no difference between the two models. Therefore, it is likely that model 3 is better than model 2. Since these statistics indicate that the more complex model of model 3 is going to provide better results than the simpler model, I would suggest the more complex model would be most appropriate at drawing conclusions. Despite including additional terms in…

It can significantly be seen that race is what officers mostly look for when it comes to pulling someone over. Generally, when a police officer pulls someone over for a pretext stop, it is often someone of color who they might suspect of a crime. A study done in North Carolina from licensed drivers says, “Results suggest that Black drivers, driver age, and vehicle age and speeding are associated with state police warning stops” (Miller 123). This shows that it is more likely for a police officer…

The Numbers Gang Oral Report “This is the day that you sign your death wish. You could die today, tomorrow, you could die anytime.” This was said to a man when he got his tattoo to represent he was a new member. Normally, when someone joins a gang, they don't realize that they are giving up their safety. Not only are their gangs all over the streets, there are many malignant gang affiliations in prisons. At Pollsmoor prison, you have to belong to a numbers gang to survive. Pollsmoor prison is…

1. a. The data set consist of 44 female and 53 males. b. There are 21 people under the age range of 13-35, which account for 21.6% of the total 97 in the sample. c. The mean level of the hour spent in the office during week 2 is 47.47 hours, with the standard deviation of 17.06. The distribution is slightly negative skew (-0.237), although in an acceptable range suggest that slightly more samples spend more hours in office than the average. The distribution’s value for kurtosis (-1.005)…

Introduction Antibiotics were initially thought of as a superior drug that could kill many bacterial diseases. Prior to antibiotics, it was hard for anyone to fight a bacteria. However, bacteria are very changing and have begun being able to gain resistance against antibiotics due to overuse, not strong enough dosage of antibiotics, or improper use. By determining the resistance and cross-resistance, one may determine the the relative ability for bacteria to gain resistance to antibiotics. We…

Metabolism is a complex process in organisms that convert the food into energy for organism to function properly. Metabolic rate is typically defined as the amount of energy the organism is currently using to maintain the activity (Perkin, 2015). Since metabolism is a key in sustaining the organisms’ life, we decided to investigate the experiment about metabolic rate caterpillar, Manduca sexta. There are many techniques used to measuring the metabolic rate, but there are only best method that…

In radiation therapy, bolus is a modality that helps compensate for differences in body contours, stop skin sparring, and to raise dose buildup on the patient’s skin (Washington, p. 171). Bolus is a tissue equivalent material, but there is not just one type of bolus. Superflab is a commercial bolus that most clinical sites use, but other bolus variations are also available for use. There is no study that compares Superflab, neon green Play-Doh, orange Play-Doh, and uncooked rice for providing…

DATA COLLECTION AND ANALYSIS Data Collection This study uses a unique dataset, which is a subset of the data that has been used by Bhansali and Zhu [12]. The dataset includes estimated IT expenditure of 329 large companies for 2005. The data was collected by phone interviews using a questionnaire designed by the research team. The questionnaire was distributed to the participants before interviews. The data was collected from approximately 600 firms; since some of these organizations are…

Summary I gain a lot of insight and learning from going through the process of identifying a student, getting to know them, administering a variety of assessments, writing about and interpreting the test results, researching interventions and supports, and making recommendations based on all of the information collected. My two main takeaways are that I had some difficulties with Woodcock Johnson IV assessment and that I significantly changed my mind about the pedagogy of math. I struggled…

4.2 Multiple Regression A regression model was run to predict the wine rating from different features (fixed.acidity, volatile.acidity, citric.acid, residual.sugar, chlorides, free.sulfur.dioxide, total.sulfur.dioxide, density, pH, sulfates, alcohol) of wine in R. According to the initial analysis on the distributions of the features, many of those features are right-skewed and thus require log transformation. Forward Selection Algorithm was used to find the best predictive models for wine…
