MCQs Non-Parametric-1

Multiple Choice Questions (MCQs about Estimation & Hypothesis Non-parametric case) from Statistical Inference for the preparation of exam and different statistical job tests in Government/ Semi-Government or Private Organization sectors. These tests are also helpful in getting admission to different colleges and Universities.
