WebWhat is a Rejection Region? The rejection regions in a two-tailed t-distribution. Image: ETSU.edu. A rejection region (also called a critical region) is an area of a graph where you would reject the null hypothesis if your test results fall into that area. In other words, if your results fall into that area then they are statistically significant. WebMay 6, 2024 · The null hypothesis ( H0) answers “No, there’s no effect in the population.”. The alternative hypothesis ( Ha) answers “Yes, there is an effect in the population.”. The null and alternative are always claims about the population. That’s because the goal of hypothesis testing is to make inferences about a population based on a sample.
