Answer:
The data-mining technique that creates a report or visual representation is summarization.
Explanation:
The business world has changed drastically over the years in terms of marketing and service delivery because of growth in technology. The use of machines and internet has caused a greater need for access and analysis of information in such a way that can make a business thrive in the market. This means that most businesses have to look into better data-mining techniques that can assist them in the competitive business environment.
The different data mining techniques include; association-rule learning, classification, summarization and regression. They are explained further as follows:
1. Association-rule learning: this is a machine learning technique that discovers a relationship between large databases using the concept of strong rules.
2. Classification: this technique finds similarities in features of two or more data sets and groups them into the same category.
3. Regression: this is a predictive technique that is used to identify and analyse the likelihood of a specific variable.
4. Summarization: this technique takes the results from the data and puts it in a way that it is short and understandable by most people. It usually involves the use of tables and other data summarization software like Excel sheets to represent the data in a way that conclusions can easily be drawn. Data summarization is important especially in the digital world where large amounts of data are available for analysis and transfer. This technique helps in breaking down huge data into short comprehensible reports that can easily be used for quick decision making.

Answer:
A. Movement on the PPC
B. Rightwards / Outwards shift of PPC
C. Less Concavity of PPC
Explanation:
Production Possibility Curve is combination of two goods that an economy can produce, given resources & technology (efficient utilisation).
- It is a downward sloping curve as more of one good can be produced by sacrifising other good, same resources & technology.
- It is concave curve because of increasing marginal opportunity cost, i.e increasing amounts of a good to be sacrifised to gain additional amount of other good, as resources are not equally efficient in production of both goods.
- Points on PPC reflect full utilisation, points under PPC reflect under utilisation, points above PPC are unattainable.
a) A disagreement between persons favouring more domestic welfare spending or national welfare spending : Is just an issue of reallocation of same resources, technology. So, PPC doesn't change & there can only be movement on the PPC (more of one good, less of other good)
b) An increase in population : leads to increase in human resource & hence the PPC shifts outwards / rightwards as the production potential of economy rise with more human resource.
c) Technological change that make resources less specialised : would reduce resources' efficiency gap in production of two goods. So, Marginal Opportunity cost reduces & hence the PPC becomes less concave.
Answer:
The correct answer is d. enriched.
Explanation:
The enrichment of tasks is a system that seeks to redesign jobs, increasing motivation and job satisfaction among workers. Therefore, the main objectives of the enrichment of the tasks are:
-
Increase the effectiveness of work organization.
- Provide jobs that are stimulating for the person.
The advantages achieved by implementing this system in the organization of the company are:
-
Feeling of satisfaction and motivation among workers: it breaks with the monotony and / or repetitiveness of the work.
- Workers are given a greater capacity for autonomy and responsibility in the tasks they carry out: as responsibility increases, workers may be encouraged to participate more frequently in decision-making, as well as in the solution of technical or organizational problems (proposals and suggestions).
- Better use of workers' capacities: with the new distribution of tasks, synergies may arise during collaboration between departments or even within the same.
- Improvement of personal relationships at work: greater collaboration during the performance of different tasks leads to increased communication and dialogue among all, thus achieving a better working environment.
- Greater involvement of workers: it is necessary that individuals know their role within the organization, the importance of the task they perform, as well as the results of it.
- Simplification of company structures: by redesigning jobs and their functions, a simplification of the organizational pyramid is achieved, resulting in a horizontal structure or flat organization. This allows workers to make their own decisions that report to a single manager, there is no intermediate link that limits the innovative capacity of the worker.
