Abstract
The existing paired
t
-test under classical statistics cannot be applied when the data is obtained from the complex process, having interval, uncertainty, indeterminacy, and incompleteness. In this paper, the modification of the paired
t
-test under neutrosophic statistics is proposed. The testing criterion of the proposed paired
t
-test is given. The application of the proposed paired
t
-test is given using the interval quality control of clinical laboratory data. From the analysis, it can be seen than the proposed test is quite effective and informative to apply for testing the measurement tools in the clinical laboratory.
