MCQs Hypothesis Testing 1

The post contains MCQs Hypothesis Testing quiz from Statistical Inference for the preparation of exams 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. The MCQs Hypothesis Testing Quiz will help the learner understand the related concepts and enhance the knowledge. Let us start with Online MCQs Hypothesis Testing with Answers.

  1. i have read in a MCQ that the power of test relate to both type 1 and type 2 error. as much as i read in my book it depend upon type 2 error please guide me about this query?
