Can null hypothesis be less than
WebA null hypothesis is rejected when the P-value is less than the level of significance, α. Therefore, if the null hypothesis would be rejected with a level of significance of α , then the P-value is less than α. In this problem, since the null hypothesis is rejected, the P-value is less than α = 0.05. WebApr 29, 2024 · Alternative Hypothesis (H A): The sample data is influenced by some non-random cause. If the p-value of the hypothesis test is less than some significance level (e.g. α = .05), then we can reject the null hypothesis and conclude that we have sufficient evidence to say that the alternative hypothesis is true.
