Abstract

Supply and Demand mismatch problem is faced by almost each and every company in the world. Some companies face severe supply related problems, some encounter demand related issues while some other face severe inventory related problems. While some companies have supply side constraint to match demand, the main issue that always troubles organizations is the problem of matching a variable demand pattern with the given constraints on the supply side. There are several reasons for supply demand mismatch, with production constraint, supply uncertainties, transportation uncertainties and demand fluctuations to name a few. Demand cyclicity and market uncertainties are some Continue reading...

Statistical Test Proposal

Enabling accuracy in research findings requires the appropriate use of statistical tools to synthesize the collected data. For this problem oriented policing field test study, the chosen approach is the mixed methodology, which encompasses the use of both qualitative and quantitative methods. As such, the use of statistical tools is essential in drawing out the findings of the POP field test study. Descriptive statistics will be the primary tool to use in interpreting the gathered data.

Definition of Descriptive Statistics

In descriptive statistics, it is important to reduce the large amount of data into a more manageable size that the readers can easily Continue reading...

Summary
Background. Children with autism have severe and persistent impairments in social interaction and communication skills, affecting their participation in daily occupations at play, leisure and school and in personal care activities, thus requiring intervention. Intervention in the form of applied behavior analysis involves teaching skills in discrete steps. The unique capacities of the child require focus to foster new learning, and is done using the concept of closed circles of reciprocal communication, called Circles of Communication (CoC). Floor Time Play (FTP) is an intervention technique representing this approach, and involves moving the child through six developmental milestones (self-regulation, Continue reading...

Executive Summary

Statistical analysis was done on the aluminum manufacturing data. Using appropriate tests, some relationships were established. First, sheet metal grade aluminum has the highest production output at sections 1 and 2. However, the standard deviation values are also highest at these two sections. Second, there is evidence that the produced amount of electrical grade aluminum is significantly different (probably higher) than the sheet metal grade aluminum made. Third, there is evidence that the bauxite consumption the bauxite consumption is significantly different (probably higher) than the purchasing policy of 4.2 tons per pot. Lastly, power Continue reading...

A government has the responsibility of ensuring economic growth and social welfare or life standards. To achieve both, it needs to apply correct economic mechanisms and tools like exchange rate regimes. The major dilemma lies between a fixed and floating or flexible exchange rates. The advocates of floating rates favor the independence of monetary policy along with its benefits while the proponents of keeping the exchange rate fixed cite low inflation, price control, better investment, and trade stability as the benefits of rate fixation. Their adversaries consider pegging capable of reducing investment and trade stressing on the possibility of Continue reading...

Introduction

The total variety, number and vastness of the living organisms together is called as biodiversity. It may hence also be explained as the variability of total life on earth. When we talk about the variability of life forms in biodiversity, it refers to two main aspects, though – the total number of different living forms and the way that they are different from each other. As Convention on Biological Diversity expertly puts it, the variability of life forms is measured from all known sources – terrestrial, aquatic, inter alia and from other ecological ecosystems available on earth (Hens & Boon, 2003).

The problem of widespread smoking is undoubtedly something that every country worldwide faces. Its negative impacts on health are already well-established that it has already prompted various authorities worldwide to take an action and reduce its debilitating effects on people—both smokers and non-smokers. In light of such efforts, various methods to persuade smokers to quit smoking tobacco and cigarettes, especially in public places, have been promoted and among these is the use of what is now called the electronic cigarette or e-cigarette.

Total number of words: 2,960

In any given context, people always find themselves in need of a helping hand or any kind word that would provide guidance and wisdom, for them to discern the best actions that would lead them to their goals. Counseling is one act of “helping an individual overcome barriers and maximize growth” (Hess, Magnuson, & Beeler, 2015, p.9). This is not an easy thing to do, since there is a dire need for the counselor to help the individual increase in their adaptive functioning, so that the person may learn how to survive challenges. The act of counseling is actually a “ Continue reading...

Create an appropriate graphical display for total box office gross.

The variable I choose for this question is adjusted total box office gross because this variable is adjusted using consumer price index of 2008. This means that total box office gross is now measured in the terms of dollars in 2008 and can be comparable, because the values are “cleansed” from inflation factor.
This data may be represented appropriately with a number of different graphs. In my opinion, the best choice is to construct histogram of the data. In statistics, a histogram is used to visualize the distribution of the studied variables. Since in this case we want to Continue reading...
