An application of the shortest confidence intervals for fraction in controls provided by Supreme Chamber of Control

Summary/Abstract: In statistical quality control objects are alternatively rated. It is of interest to estimate a fraction of negatively rated objects. One of such applications is a quality control provided by Supreme Chamber of Control (NIK) to find out a percentage of abnormalities in the work among others of tax offices. Mathematical details of experimental designs for alternatively rated phenomena are given in Karliński (2003). Zieliński (2010b) investigated statistical properties of those experimental designs. In the paper, the application of the shortest confidence intervals for fraction in experimental designs is shown. Those intervals were proposed by Zieliński (2010a).
