Observing a system or process while it is in operation is an important part of the learning process, and is an integral part of understanding and learning about how systems and processes work.

Hypothesis testing allows the comparison of the two formulations to be made on objective terms, with knowledge of the risks associated with reaching the wrong conclusion.

In such a single factor experiment with a completely randomized design, the levels of the factor are randomly assigned to the experimental units in some cases, randomly selecting experimental units from each level of the factor.

In any experiment, variability arising from a nuisance factor can affect the results. Generally, we define a nuisance factor as a design factor that probably has an effect on the response, but we are not interested in that effect.

Suppose that an experimenter is studying the effects of five different formulations of a rocket propellant used in aircrew escape systems on the observed burning rate. Each formulation is mixed from a batch of raw material that is only large enough for five formulations to be tested.

A mathematical model which specifies complete probability distribution of the number of individuals in a given system at each point of time is a stochastic model.

Suppose that one particle can produce a random number of k new particles. Each of the new particles produces another random number of new particles. We assume that the particles act independently of each other and that every particle has a probability pk of producing k new particles (for k = 0, 1, 2, , . . ).

We consider a special case where the outcome of any trial depends on the outcome of the directly preceding trial, and only on it. A stochastic process with this property is referred to as a Markov Chain (or a Markov process).

An absorbing Markov Chain contains only absorbing and transient states. If the number of states is finite, a Markov process starting from any transient state will eventually end in one of the absorbing states. Suppose that there are s absorbing states and t transient states so that the transition matrix P is order (s + t).

In this Chapter, we develop probability models for some special cases of birth-and –death process involving the population size within a given system at time t. The probability generating function can be used to analyze the process in the case where the actual probability distribution cannot be obtained. We also obtain deterministic models corresponding to the given probability models.

This course will provide you with an introduction to the sociology of work. It is designed to provide you with a broad overview while giving emphasis to specific topics in detail. It is beyond the scope of this unit to cover the field of work and industry in entirety.

Computer system has three components namely: Hardware, software and liveware (computer user). A system is a collection of different entities that collectively work together to achieve a desired goal. Examples of systems are human body, social system, school system etc. A computer system is a collection of three components namely hardware, software and liveware entities that work together to receive, process, manage and present information in a meaningful format using computers

The term environment comes from a French word ‘environmer’ meaning the surrounding. It is perceived as that part of the world with which humans interact, a sum of the total natural and socio components which are or may be in direct interaction with humans. The environment is also seen as a social construct made up of four dimensions; the biophysical, social, economic and political dimensions. The environment with its dimensions form a system whose dimensions interact affect and is affected by other dimensions. When any of the dimensions is affected negatively or positively the entire environment is affected. Environment is a system made up of components that interact with each other, the environment is complex system affecting the development of humanity, and it provides resources for economic growth and for ecological and social wellbeing.

Management is a technique of leadership or a means of coordination or cooperation. It is systemized knowledge based on general principles which are verifiable in business practice. The management; plans, organizes, motivates directs and controls six ‘m’ – men, money, materials, machinery, market and minutes (time).

As a general rule, opinion evidence is inadmissible; a witness may only speak of facts which he personally perceived, not the inferences drawn from those facts:

The purpose of the course is to acquaint students with knowledge on theories of human development and the human development process so that they can apply these in their teaching profession.

Schooling refers to the act of physically attending a formal institution of learning e.g. primary or a secondary school. It involves systematic promotion through the grade range governing the learning institution with the assumption that at the end of their institutionalized cycle some learning will have taken place.

The general objective of this course is to enable students and other professionals skills which they may need to perform effectively their activities in the university and later on life.

Phonetics is a discipline that deals with the systematic study of all speech sounds which human beings are capable of producing. It provides means of identifying, recognizing, describing and classifying virtually all the speech sounds that can be produced by the human vocal tract.
