In this study, a Shewhart‐type control chart is proposed for the improved monitoring of process mean level (targeting both moderate and large shifts which is the major concern of Shewhart‐type control charts) of a quality characteristic of interest Y. The proposed control chart, namely the Mr chart, is based on the regression estimator of mean using a single auxiliary variable X. Assuming bivariate normality of (Y, X), the design structure of Mr chart is developed for phase I quality control. The comparison of the proposed chart is made with some existing control charts used for the same purpose. Using power curves as a performance measure, better performance of the proposedMr chart is observed for detecting the shifts in mean level of the characteristic of interest.

Corruption is one of the world's most widespread political problems. It can be found on international, national and sub-national level. Access to education and other socio-economic services is of utmost importance for all humans. It is still not exclusively based on merit, but often rather unfairly distributed and allocated depending on corrupt local bureaucrats. We utilize a micro level measure of corruption based on the personal experiences of individuals, which realistically represents the linkage between individuals and public office holders. For the empirical analysis, we utilized the Afrobarometer survey of 36 African countries that contains information of more than 50,000 citizens. Corruption is found being negatively correlated with the access to water, education, health and paved roads, while positively associated with access to sewage system and having no significant association with access to electricity grid. The findings reveal that in order to expand the access to basic socioeconomic services, governments need to control corruption in public offices on a daily basis.
