WebSep 30, 2024 · You can reject the null hypothesis if you're following one principle of the scientific method, called falsifiability. This principle states that further research can prove false the results of a previous study. As a researcher, it can be easier to prove that a hypothesis is false, rather than claim that the statement is comprehensively true. WebHypothesis Testing. A rejection region (or a critical region) is the region (denoted by RR) that specifies the values of the observed TS for which the null hypothesis will be. 1. Figure out mathematic tasks. Math is a subject that can be difficult for some students to grasp.
