WebbThe level at which a result is declared significant is known as the type I error rate, often denoted by α. We try to show that a null hypothesis is unlikely, not its converse (that it is likely), so a difference which is greater than the limits we have set, and which we therefore regard as "significant", makes the null hypothesis unlikely.

WebbType 1 Error In Hypothesis Testing Definition In hypothesis testing, the conclusion is to reject or fail to reject the null hypothesis. When the null hypothesis is true, but the test decision is to reject the null. It results in an error called type I error. Overview of Type 1 Error In Hypothesis Testing Webb2 maj 2024 · The Type I error is the probability that, given the null hypothesis is true, the rejection criterion is met. In your case, this means that X is Poisson distributed with λ = 4, and you find that X ≤ 1; i.e. Pr [ X ≤ 1 ∣ λ = 4] = Pr [ X = 0 ∣ λ = 4] + Pr [ X = 1 ∣ λ = 4] = e − 4 4 0 0! + e − 4 4 1 1!.
