THE CONCEPTS OF NEGATIVE BINOMIAL DISTRIBUTION AND ITS APPLICATIONS IN REAL LIFE. BY OWUSU BRIGHT. INTRODUCTION In centuries, human activities where outcomes are described either as success or failure, has been a concern in the history of probability and statistics. In the act of tossing a coin, throwing a die to obtain a 6, either a machine work or fails, a student passing an exam or not and so on are events whose end results are either a yes or no, good or bad, present or absent, success or…

My initial thoughts and feelings walking into the courthouse were one of nervousness, and excitement. I was nervous to be in the presence of criminals, and to go through security. Also, just being around people with such high authority is intimidating. I was really excited though, I have always been interested in the workings of a trial. I was anxious to hear what the case I was sitting in on was all about, and do come up with theories and verdicts of my own. The spatial arrangement in the…

tabulated using Unified Soil Classification System (USCS) method, which is non-laboratory test and 2 classification of soils based on laboratory test. The two laboratory test classify soil methods are Classification of soil based on particular size distribution and Classify soil based on Atterberg Limits. The soil samples from sites known as bore hole and called BH1, BH2, and BH3. I.b. Problem Description Sustainable Earth firm commissioned to conduct a feasibility study for an earthwork…

Each powder mixture has unique characteristics, and so have a unique optimization curve to achieve an acceptable state of uniformity and particle size distribution. Many blending units are available which offer differing shear, convective and dispersion properties on the powder bed. Convective forces refer to large groups of particles moving in an orthogonal direction to the axis of rotation. Dispersion…

Diagnose Another issue relates to UA’s distribution strategy of only operating 2 leased distribution facilities located closely to each other in Glen Burnie, Maryland, United States. Before deeply analyzing this problem, the fact needs to be noticed is that UA outsources nearly 100% of their manufacturing from Asia, Latin America and other areas. All finished products that are manufactured overseas are shipped to the distribution centers in Glen Burnie first, then they will be distributed to…

Particle size distribution Introduction The purpose of this lab was to determine the particle size distribution of a particular soil sample by carrying out sieve analysis and hydrometer analysis tests. For the sieve analysis test, a graph for percent finer versus the grain size was plotted from the data collected. The graph was used to determine whether the soil sample was fine-grained or course-grained. Calculations for uniformity and gradation were then done to determine whether the soil was…

Figure 1. Chi Square Test for Niche lab conducted at Owings Mills North.Behaivors of several species of birds (Tufted titmouse, dark eyed junco, black-capped chickadee, northern cardinal, mourning dove, purple finch, house sparrow, and white breasted nuthatch) were observed at feeding station. The three possible behaviors are feeding at the feeder, feeding on the ground, or feeding in the tree. Assignment questions 1-4 Given the results of the chi square, the birds feeding behavior are…

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…
