Poisson distribution

In definition, probability refers to the measure of the likelihood of an event happening. The probability for any event occurring falls between 1 percent and 100 percent thus meaning that the interpreted meaning of a probability equals the subject meaning held of the probability (Grinstead et al, 1997). However, it is worth noting that the application of probability or assigning of probability to the events in the effort to gratifying the axioms of probability follows some rules or basics…

observation periods. Slide 3: Our null hypothesis states that no difference occurs. If we overlapped the distribution curves of the two groups or the two observation periods, we would find that they were similar in shape. Slide 4: If the differences in the mean scores between the groups or observation…

Quantitative risk analysis is the one which follows the Qualitative analysis, and gives a numerical priority rating to project risks (PMI, 2009). Based on the PMBOK (PMI, 2013) quantitative risk analysis “… is the process of numerically analyzing the effect of identified risks on overall project objectives (p. 333).” This is also a process for the PM and project team to get risk data to support making decisions, which can help to reduce project uncertainties (PMI, 2013, p. 333). Based on the…

A sample revealed three bags of 56, two bags of 57, one bag of 55, and two bags of 58. To test the hypothesis that the mean candies per bag is 56, how many degrees of freedom are there? * 8 * 9 * 7 * 1 Which of the following is most appropriately displayed with a frequency table? * What percentage of people prefer Hunt's brand ketchup * The home location of the most valuable customers * The relationship between gender and job performance *…

Pre-Lab Questions 1. A population is a group of the same species that live in the same area and sometimes compete or can mutually benefit one another. A group of organisms will only be considered a population if they live in the same area in space and time. N is the true population size for a given group of organisms. This number is unlikely to be completely known. Whereas N hat is an estimate of population size. 2. There are two methods of sampling, direct and indirect. Direct sampling is an…

This should express that a normal distribution will always follow this rule. Therefore, if one wanted to ensure that home sales were still tracking to normal distribution, a quick calculation would ensure it. If home sales or prices experienced an unusual circumstance, this calculation would allow one to see if the data were skewing positively or negatively. It is clear from the data in Table II that all four of the calculations are tracking to a normal distribution and all data points are…

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…

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…
