Detailed explanation-1: -If the tabulated value in hypothesis testing is more than the calculated value, than the null hypothesis is accepted. Otherwise it is rejected. The last step of this approach of hypothesis testing is to make a substantive interpretation.
Detailed explanation-2: -A scientific hypothesis is accepted if there is no way to demonstrate that the hypothesis is wrong. Science experiments are used to prove or disprove a hypothesis. If the results do not agree with the hypothesis, the experiment can be performed again using different variables to further test the hypothesis.
Detailed explanation-3: -For these reasons, in null hypothesis significance testing, one can either reject the null hypothesis, or fail to reject it, but can never accept it.
Detailed explanation-4: -After a performing a test, scientists can: Reject the null hypothesis (meaning there is a definite, consequential relationship between the two phenomena), or. Fail to reject the null hypothesis (meaning the test has not identified a consequential relationship between the two phenomena)
