Chi- Square Goodness of Fit Testing Assuming Equal Expected A handful of students loves numbers and selects a major in Finance, Statistics, or Marketing. While others prefer a major in Leadership or are undecided. Historically, the MBA program at Whatsamatta U has about 40% of their students electing Leadership as their major, 30% selecting Finance as a major, 20% choosing Marketing, and 10% are undecided. Conducting a Chi-Square Goodness of the Fit Test revealed that the class of 200 students…
testing, the critical value is a number that separates a region where the null hypothesis will not be rejected from a region where it will be rejected. It is achieved at a particular percentile range and is then determined using a chart, known as the distribution topic.” The equation below states the critical value at 5% significance level: C.95 =21.026 * The .95 is taken from 100%-5%=95% *The 12 is from the degrees of freedom Lastly, I found what conclusion could be drawn regarding the…
Pectin yield was determined as weight of dry pectin against the weight of initial residues multiplied by 100%. Y=100(P/Bi) Where Y is the extracted pectin yield (%), P is the amount of extracted pectin in grams and Bi is the initial amount of sweet potato residues used to extract pectin. Equivalent weight and Degree of methoxylation The equivalent weight was determined according to the method by Barretina et al., (Barretina et al. 2012). 0.25g pectin was wetted with 5ml ethanol and topped…
Drosophila Melanogaster, or better known as the common fruit fly, is found all over the world and referred to as the cosmopolitan species (Mitrick, 2010). This fruit fly has three main body parts, which include the head, the thorax, and the abdomen. On males, the bottom half of the abdomen is black, while on the female, each segment of the abdomen is striped black. Drosophila have four main stages to their life cycle. These include: egg, larva, pupa and adult. The eggs small and translucent eggs…
Hypothesis This study attempts to assess two research hypotheses. Our hypothesis answers the research question, what difference, if any, can be found between the two concentration when describing dissertation characteristics? Our first hypothesis (H1) states that clinical track dissertations are more likely to be experimental than administrative track dissertations. Our second hypothesis (H2) states administrative track dissertations are more likely to have advanced statistical analyses than…
built-in LA-950 Horiba software. The particle volumetric diameters were expressed as D10, D50 and D90, indicating the diameter under which 10%, 50% and 90% of the sample resided. Following equation was used to calculate the broadness (span) of size distribution. All measurements were done in triplicate for each…
Results In the lab, 478 trials were conducted using a total of 956 crickets. The 478 pairs resulted in 264 wins for the resident cricket and 214 wins for the intruding crickets. These results produced a chi squared value of 5.230. The p-value calculated from this lab was .022. A chi squared value of .022, less than the benchmark of .05 means the data from the lab was significant and statistically rejects the null hypothesis that there was no correlation between residency and aggression…
Technology About technology policy, Amazon has been committed to improve logistics efficiency and cost savings. Because the amazon sales are very large, so inventory and logistics management requires more reasonable technical methods. A good management system not only can improve the efficiency of operation, also can reduce the risk of inventory and logistics management, to avoid unnecessary loss. So in this part, we will talk about Amazon’s Bin System which is Amazon’s warehouse management…
Where will I be in ten years? This is a question I often reflectively pose to myself. How can one simple question, containing just seven little words, be full of such endless possibilities and outcomes? Ten years ago, I would not have said that I would be a full time student, on my way to earning a degree in Sociology. Ten years ago I was still in my career of choice, truck driving. One could say I was just “spinning my wheels”, so to speak. A truck driver is certainly not something I had…
In the Maritime Industry, there are two types of shipping. Liner shipping and Tramp Shipping. In order to manage these two forms of shipping, a port agent or a port agency is designated person or agency held responsible for handling shipments and cargo, and the general interests of its customers, at ports and harbours worldwide, on behalf of ship owners, managers, and charterers. Specifically, there are two types of port agents. Liner Agent and Tramp Agent. A roles and responsibilities of a…
