Which of the following best describe(s) the significance level? A)it is the probability of rejecting a true null hypothesis B)it is denoted by $\alpha$ C)it is the probability of making a Type I error D)it is used to define the boundary of the reject H₀ region E)all of the above

Question

Quizplus · Accepted Answer

The significance level, often denoted by alpha (α), is the probability of rejecting the null hypothesis when it is actually true, which is the definition of a Type I error. It is used to define the critical boundary beyond which we reject the null hypothesis. Therefore, all the statements A, C, and D correctly describe aspects of the significance level, making E the correct choice.

Which of the Following Best Describe(s) the Significance Level? A)it α\alphaα
