WebJun 7, 2016 · Why the null hypothesis should always be written as an equality. It is often stated that the null hypothesis should be written as an equality (see for example here ), like for example μ A − μ B = 0, while the alternative uses an inequality (for example, μ B > μ A ). I think that this kind of null hypothesis is called "simple". WebJun 16, 2024 · If the p-value is not less than the significance level, then you fail to reject the null hypothesis.
