Determine probability of type 1 error
WebOct 17, 2024 · Understanding Type II Errors. In the same way that type 1 errors are commonly referred to as “false positives”, type 2 errors are referred to as “false negatives”. Type 2 errors happen when you inaccurately assume that no winner has been declared between a control version and a variation although there actually is a winner. 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.
