The Statistical Study Of The Market State Of Kwara Poly Pure Water And Its Conformance To People Specification


This project deals with the statistical study of market state of kwarapoly purewater and its conformance to specification.

The data used in this project work was collected through personal interview of the vendors within the campus on attribute quality and the market state.

Attribute control chart (p-chart) and cause and effect diagram was employed to measure the conformance to specifications. Further analysis to determine the market state was based on comparism of two independent sample mean.

The result of the analysis shows that the process is out of control i.e the analysis on proportion defective shows that there is assignable cause of variation in the process. Furthermore, there is significance difference between the market state of kwarapoly purewater and other purewater products before.

1.0 Introduction

Water is a chemical compound with the chemical formula H2O. A Water molecule contains one oxygen atom and two hydrogen atoms connected y covalent bond. Water is a liquid at temperatures above 00c (273.15k, 320F) at sea level, but it often co-exist on Earth with its solid state, ice and gaseous state (water vapor or steam). Water also exists in a liquid crystal state near hydrophilic surface.

Water covers 71% of Earth’s surface and is vital for all known form of life. On Earth, 96.5% of the planet’s water is found in oceans, 1.7% in groundwater, 1.7% in glaciers and the ice caps of Antarctica and Greenland, a small fraction in other large water bodies and 0.001% in the air as vapor, clouds (formed of solid and liquid water particles suspended in air) and precipitation. Only 2.5% of Earth’s water is fresh water and 98.8% of the water is in ice and groundwater. Less than 0.3% of all freshwater is in rivers, lakes and atmosphere and an even smaller amount of the Earth’s fresh water (0.003%) is contained within biological bodies and manufactured products.

Water on Earth moves continually through the hydrological cycle of evaporation and transpiration (evapotranspiration), condensation, precipitation and runoff usually reaching the sea. Evaporation and transpiration contribute to the precipitation over land.

Safe drinking water is essential to humans and other life forms even though it provide no calories or organic nutrients. Access to safe drinking water has improved over the last decades in almost every part of the world, but approximately one billion people still lack access to safe water and over 2.5 billion lack access to adequate sanitation. There is a clear correlation between access to safe water and GDP per capital. However some observers estimated that by 2025 more than half of the world population will be facing water-based vulnerability. A recent report (November 2009) suggested that by 2030, in some developing regions of the world, water demand will exceed supply by 50%. Water plays an important role in the world economy, as it functions as a solvent for a wide variety of chemical substances and facilitates industrial cooling and transportation. Approximately 70% of the freshwater used by humans goes to agriculture.

1.1 Historical Background

The Kwara state polytechnic, Ilorin, was established in 1972, under the edit no 4 which has now been replaced by edit no 1984 with the objective of upbringing various people for acceleration of economy development in Kwara state and in Nigeria as a whole.

The polytechnic was established and open by the then governor of Kwara state, col. David Bamigboye. The decision to establish the polytechnic was announced during the launching of the four year development plan in 1971.

The college eventually came into existence and come on operation in January 1973 with administration machinery patterned closely after the existing university in the country.

As it inception in 1973, the polytechnic has 110 students, one member of academic staff and three senior administrative staffs (including registrar).

The main proposal for the establishment of the polytechnic was to develop what is needed and not what it can lay her hand on.


1.1.1 Kwarapoly Purewater

The production of purewater in the institute started in October 2012. The need to produce the school own purewater in order to meet the challenges and to be among the purewater producing institutes of learning in the country and also to serve as source of revenue generation. Hence, the need for production of purewater for timing population in the ecosystem (community).

The WHO standard on water emphasized the need for quality water that save life and conform to specifications.
From the inception of kwarapoly purewater production in the institution, the seller/vendors of other purewater product was stopped and only the institute purewater was in circulation and a lot of complain by the consumers of the purewater.

The question of conformance to taste and durability of the packaging then arises. The unsatisfactory conditions of the purewater lead people to avoid drinking it. Instead, some people prefer buying and drinking bottle water while some that cannot afford bottle water do bring water from their home and those that cannot afford the two options, with no other choice take the purewater with risk.

1.2 Significance of Study

The research work will play a vital role in acceptance and viewing the complaint of the customers on the satisfactory state of the product. This will also go along in checking and improving services.

The need to have a quality purewater and the need to be one of the leading product service in the state, since quality is about improvement.

1.3 Scope of Study

The research work covers only the purewater vendors in the campus and the targeted consumers in the campus only with specific interest on Kwara state polytechnic water.

1.4 Limitation

The research work is faced with a lot of challenges among which are lack of access to data at the water port, non-response and time factors.

1.5 Aims and Objectives

  1. To examine if the purewater is in statistical control.
  2. To examine if the purewater conform to specifications.
  3. To examine cause and effect if not in statistical control.
  4. To measure the market state of the purewater.

Summary, Conclusion and Recommendation

5.0 Introduction

This chapter reveals a comparative result of all the computations done so far in the course of this project analysis. Both the result obtained when attribute control chart is employed, cause and effect diagram as well as comparism analysis are completely stated here for quick and clear understanding.

5.1 Summary

Based on the result of the analysis of data;

  1. The process is not statistically stable (not under control).
  2. There is difference between the average number of days to sale kwarapoly purewater and other purewater products.
  3. There is difference between the variability of kwarapoly purewater and other purewater products.
    Kwarapoly purewater has poor market sales.

5.2 Conclusion

From the analysis, I inferred that there is assignable cause of variation in the process of kwarapoly purewater. This can be attributed to source of water used, improper purification and poor packaging.

The analysis also shows that 18.4 bags ≈ 18.5 bags of kwarapoly purewater are purchased by a vendor per day while 26.03 bags ≈ 26 bags of other purewater product are purchased by a vendor per day. It took 2.2 days ≈ 2days, 5hours and 1.53 days ≈ 1day, 12 hours respectively to sell the quantity purchased.

The analysis also reveals that selling kwarapoly purewater incur higher risk than selling other purewater product of 1.14% against 0.46%.

Finally, the attribute characteristics of kwarapoly purewater (tasty and odor) had lead to its poor sales in the market.

5.3 Recommendation

Based on the above conclusion, the school authority intervention will be required to monitor the process in which the purewater is produced.

By impacting quality into the product; check the source of the water used and tender its hardness to bearest minimum to address the tasty. It should be well purified to address the odor.

The superiority of the quality o nylon used for packaging should also be checked to reduce wastage of the product and if at all there is leakages, it should be changed for the vendors to save them from shortages.

Finally, the purewater should be registered with NAFDAC to support its standard.
