WebThe logic of null hypothesis testing involves assuming that the null hypothesis is true, finding how likely the sample result would be if this assumption were correct, and then making a decision. If the sample result would be unlikely if the null hypothesis were true, then it is rejected in favour of the alternative hypothesis. WebFeb 2, 2024 · To decide the fate of the null hypothesis, just check if your t-score lies within the critical region: If your t-score belongs to the critical region, reject the null hypothesis and accept the alternative hypothesis.
