Abstract

An application of variable control chart in modelling American honey spirit bottle in Beta Glass plc Ughelli. Statistical quality control has become a vital tool employed in the field of quality assurance in both product and service providing industry in order to meet the set management standard and keep the process in control so as to remain in the global business. This study, therefore: an application of variable control chart in modeling American Honey spirit bottle is a research work aimed at applying the mean and range chart to monitor 20 samples of size 5 Mould from machine 21A export line that was subjected to a comprehensive strength test measured in psi. Data was collected secondarily from the quality assurance Department of Beta Glass plc, Delta plant, Ughelli. Data was analyzed using Minitab 17.0 version. The mean and range chart was used to analyze the data and the runs test was also carried out to access the process randomness. It was discovered that both the range and mean chart are in statistical control. It was also observed that the process is random as revealed by the runs test hence the null hypothesis was accepted at a 5% level of significance.
