In the airplan example you are talking from a quality control point of view, so as if my level of significance increases this will decrease the consumer's risk ( i.e probability of accepting poor quality that may cause a certain malfunction ?

Are there any questions that will definitely come up? E.g. E(X) and Var(X)?

Thanks
