Type II Error - Definition, How to Avoid, and Example
WebIn example 2, if p is less than 0.40, you would still not want to build the cafeteria. After all, it could be the case that 30% or 10% or even 0% of the people are interested in the meal plan. If you were to set H_0: p = 0.40, then you would ignore all these less than options, so we need the less than or equal sign. Comment. WebThe test power is the probability to reject the null assumption, H 0, when it is not correct. Power = 1- β. Researchers usually use the power of 0.8 which means the Beta level (β), the maximum probability of type II error, failure to reject an incorrect H 0, is 0.2.
