Stats null and alternative hypothesis
Null and alternative hypotheses are similar in some ways: 1. They’re both answers to the research question. 2. They both make claims about the population. 3. They’re both evaluated by statistical tests. However, there are important differences between the two types of hypotheses, summarized in the following table.

The null hypothesis (H0) … See more The null hypothesis is the claim that there’s no effect in the population. If the sample provides enough evidence against the claim that there’s no effect in the population (p ≤ α), then we can reject the null hypothesis. … See more To help you write your hypotheses, you can use the template sentences below. If you know which statistical test you’re going to use, you can use the test-specific template sentences. Otherwise, you can use the general … See more The alternative hypothesis (Ha) is the other answer to your research question. It claims that there’s an effect in the population. Often, your alternative hypothesis is the same as your research hypothesis. In other … See more WebIt can be shown using either statistical software or a t-table that the critical value t 0.05,14 is 1.7613. That is, we would reject the null hypothesis H 0: μ = 3 in favor of the alternative hypothesis H A: μ > 3 if the test statistic t* is greater than 1.7613.
