How to calculate type 2 error probability
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. Web18 jan. 2024 · The Type II error rate is beta (β), represented by the shaded area on the left side. The remaining area under the curve represents statistical power, which is 1 – β. …
