Abstract This study examined the use of acceptance sampling technique as an efficient tool for quality assurance in deciding whether a given lot of product is to be accepted or rejected in the market. This study designed two single sampling plans with a sample size of 125 from a lot of size 1350 bread loaves and an allowable number of defectives as 4 and 6 (i.e. c=4 and 6). The result indicated that the probability of rejecting the manufacturers’ product of good quality by the consumers is...
ABSTRACT This research compare the students’ academic performance using JAMB scores and CGPA inBenue state University Makurdi, and the level at which the divergence in grades started is ofparamount importance. Two faculties in the institution were selected. The multiple regressionanalysis carried out shows that JAMB scores as well as yearly GPAs can predict the finalCGPA. From the student (t) distribution it was observed that the model contribute information tothe yearly GPA...
ABSTRACT This research work examines the effects of some factors influencing Hypertension, and the data used was obtained from the case-hypertensive patients’ record at the University of Ilorin Teaching Hospital (2007 - 2012). Basically, the target of this research are patients of infections/diseases (e. g. HIV/AIDS) that later developed hypertension. The Pearson’s Chi-square test statistic – testing for independence, the Odds ratio, Relative risk and Pearson’s product moment correlat...
The study examined the incidence of the rate of Neonatal Mortality in Nigeria. The incidence tested with use of Time Series Analysis (ARIMA). The trend plot of the incidence shows that there has been steady decrease in the incidence rate over the years. The series was stationarity using the Augmented Dickey-Fuller (ADF) Test, the result found to be stationary. The Correlogram of the incidence also supports the stationarity of the series at 1% level of significance. The model that best describ...
ABSTRACT The research focuses on the impact of non-oil exports on Nigerian economy. It employs the documentary method in retrieving secondary data for the study. The data is retrieved from the CBN statistical bulletin for the year 2016. The method of data analysis is the ordinary least square (OLS) method of multiple regressions using the Microfit software. At the end of the analysis, it is discovered that non-oil exports has a significant impact on the economic growth of Nigeria. I recommen...
Logistic regression model deals with the relationship that exists between a dependent variable and one or more independent variables. It provides a method for modeling a binary response variable, which takes values 1 and 0. Further, Logistic regression is useful for situations in which you want to be able to predict the presence or absence of a characteristic or outcome based on values of a set of predictor variables. It is similar to a linear regression model but is suited to models where th...
ABSTRACT Water as an essential commodity plays a major role in national development, the availability of water through pipe borne to individual, communities, and the country at large will help in achieving the New Millennium Development Goal (MDG7), hence the constant study, analysis and forecast for supply of water using past water supplied. The supply of pipe borne water from 2009 to 2015 was examined with the aim of developing a working model to forecast future supply of pipe borne water...
ABSTRACT Stillbirth remains a public health problem with an estimate of 2.6 million stillbirths in 2015 of which 98% occurred in low- and middle-income countries and over three-quarters of these occurring in Sub-Saharan Africa (SSA) and south Asia. Further, only ten countries carry the burden of over 65% of total stillbirths in the world including Nigeria in the second position. The objective of this analysis is to estimate stillbirth rates and identify the determinants of stillbirth in Haji...
ABSTRACT The primary aim of this project is to estimate the long run relationship between economic growth and currency devaluation. This project investigated the impact of currency devaluation on economic growth of Nigeria. This was achieved through a review of literature. In order to generate the necessary data for this research, the Central Bank of Nigeria Statistical Bulletin of and publications of the National Bureau of Statistics were used for the period of 2008 to 2017. The error co...
ABSTRACT For schools to be effective, computer literacy should be demonstrated through computer availability as well as student’s awareness and usage of library related website. The research design is a descriptive survey which comprises a sample of 383 students randomly selected from a population of YABATECH students. The research instrument is a well-designed questionnaire for students. The statistical tools employed in to analyze the data are frequency and percentage distribution; t...
This study explores determinants of child mortality in Kenya using the 2008/09 Kenya demographic and health survey (2008/09 KDHS) data. Cox proportional hazard model is used and stratification method was used to handle the non-proportionality of the hazards. Kaplan Meir log rank test is used to explore the data and determine the significant variables that have association with child mortality to be used in the model. The study establishes that there is improvements in child survival over the...
ABSRACT The Kenyan CPI data for the period January 2000 to December 2017, obtained from the KNBS website, was the variable of interest, modelled as a time series variable. R was the package used for analysis. Descriptive statistics such as the mean, median, ACF, PACF, time series plots, histograms, lagged scatter plots and qqplots were employed to assess the non-stationarity of CPI after which appropriate smoothing techniques such as differencing were made use of to detrend the data. Formally...
ABSTRACT This research work was focused on the EFFECT OF LACK OF PRACTICAL TOOLS ON THE ACADEMIC PERFORMANCE OF STUDENTS in The Ibarapa Polytechnic, Eruwa. The objectives and purpose of the research work is to determine whether factors such as lack of practical tools, lack of enough practical lecturers, improvising of practical tools has any effect on the academic performance of students, also, to determine if students can cope with academics without adequate practical and equipme...
ABSTRACT The present study was conducted at Ahmadu Bello University, Zaria. The aim of the study was to determine the effect of feeds (cotton seed cake, yeast supplement, cow milking ration) and seasonal variation (dry and rainy season) on dairy milk yield. A total of 21 mid lactation cows were fed with cotton seed cake, yeast supplement and cow milking ration in the two seasons respectively and the volume of milk produced by each cow was recorded �...
Abstract: This study was aimed at determining the average performance of teams that participated at the 2014 World Cup in terms of goals scored. Bayesian approach was used to analyze this problem. There was an update of belief about the average goals scored in the tournament through the conjugate Gamma prior and the Poisson likelihood. Using the conjugate Gamma prior and Poisson likelihood, the average goals scored per team was 1.3354 and a posterior standard deviation of 0.1018. The 95%...
