The first step in building our simulation model was to confirm whether or not a normal distribution was in fact reasonable for the unknown demand of Egress ski jackets in the coming year. To do this we input Egress’ estimated demands into Best Fit. After analyzing the output (Exhibit 1 and 2) we see that […]

According to Hamdy Taha’s 1998 book (p. 607), queues are systems that require waiting in line, and studying them helps determine the efficiency of waiting lines by considering factors like queue length and wait times. Identifying the suitable service for a specific situation or facility is the main objective of this research. According to Render […]

Dates The data used is ETG cost data from a top national health insurance company. It includes 33 million observations from 9 million claimants. Each observation represents the annual total cost per claimant for each ETG. Policyholders without claim costs for specific ETGs are not included in the dataset. There are a total of 347 […]

The intent of this research is to find when it is more desirable to come close a distinct distribution with a normal distribution. Particularly, it is more convenient to replace the binomial distribution with the normal when certain conditions are met. Remember, though, that the binomial distribution is distinct, while the normal distribution is uninterrupted. […]

The Problem: You are in a game show and the host shows you three doors, saying that only one will give you the grand prize. After choosing one door, the host will open one of the two doors you did not choose. The host knows where the prize is and he would not open that […]

It can be noted from the above results, both methods will cause the function ln(S(t))/ will converge to the limit which is approximately 0.0558077, which is close to the true value of p of 0.055. The true value can be found based on the property of the probability distribution of ln(S(t)). We note that: as […]

Introduction Development of mathematics as a discipline of logic did not exist before about 1000 B. C. The Greek philosopher Aristotle (-350 B. C. referred to the process of optical projection of images. Leonardo da Vinci explored the disciplines of optics, geometry and mechanics. In 1492 he demonstrated the principles of optical perspectivity (MacLeish 1977), which […]

The aim of this investigation is to assess the level of reliance and establish a possible connection between two variables, keeping in mind their expected strong correlation and dependence. To ensure precise outcomes, it is vital to collect relevant data and utilize statistical methods like computing correlation coefficients and regression lines. Additionally, any anomalies that […]

I. Introduction Rice is the primary food crop in the Philippines and a staple in much of the country’s diet. It is grown in Luzon, Western Visayas, Southern Mindanao, and Central Mindanao. In 1989, around 9.5 billion tons of palay were harvested. Palay accounted for 27 percent of the value added in agriculture and contributed […]

Beginning in the 1970s, two developments dramatically changed in employee selections. First, the development of meta-analysis, arguably one of the most influential methodological developments in recent decades, made it possible to cumulate quantitatively the results of large numbers of small-scale studies, resulting in a quasi-massive-scale study. Second, the results of large-scale studies of military personnel […]

Over the past six decades or so, crude oil -? because of the products derived from it, as become highly indispensable in our everyday lives. Despite being a non- renewable resource, it is still used extensively in power generation. It can be argued that industrialization owes its development to crude oil. Even though efforts are […]

Inventory system is that it is paper less which is a cost saving mechanism. This new inventory system allows for in dept information through one entry, allows for real time where as with the prior inventory system it could be 45 – 60 days before every entity was able to view all transactions. The inventory […]

All statistical procedures have underlying assumptions, some more stringent than others. In some cases, violation of these assumptions will not change substantive research conclusions. In other cases, violation of assumptions will undermine meaningful research. Establishing that one’s data meet the assumptions of the procedure one is using in an expected component of all quantitatively based […]

Briefly discuss the two momentum strategies of Numeric Investors. First approach – Numeric Investors applies a strategy based on past changes in analysts’ estimates. They cluster the forecasts of company earnings and revise their earnings estimates incrementally, rather than making significant jumps. This approach prompts analysts to update their estimates and causes consensus estimates to […]

The question is, are wages dependent on the gender, occupation, industry, years of education, race, years of work experience, marital status, and union membership. We will use the technique of linear regression and correlation. Regression analysis in this case should predict the value of the dependent variable (annual wages), using independent variables (gender, occupation, industry, […]
