Abstract

This paper presents the statistical analysis of water pollution in yoghurt industry in Nigeria. Water pollution has brought unpleasant implications for health and economic development in Nigeria. However, despite the public and international agencies policy focus on water pollution problem, the situation in Nigeria seems degenerating and therefore demands increased attention. The regression analysis was carried out to show the contribution of some pollutants like in the total population recorded in yoghurt industry in South West, Nigeria. The pollutant (Biochemical Oxygen Demand) i.e. Variable from the analysis plays a major hazard effect on the total pollution recorded by the industry which can cause hazard to populace when consumed. Coefficient of determination calculated i.e.R² = 0.9994 shows how changes in total population is completely explained by changes in the auxiliary variable i.e. pollutants. Multicollunieraity also exists in the explanatory variable which shows a higher variances and covariance of the estimate of the parameters
