Some bottles of bubble bath have gone past their expiration date. The employees want to know if the expired bubble bath produces a significantly different amount of bubbles. They know that a fresh bottle of bubble bath produces a 124 cubic inches (in3) of bubbles with a SD of 8 in3. After testing 16 bottles, they find the average expired bottle produces 130 in3 of bubbles. Imagine we KNOW that a treatment does not actually have an effect but the researcher concludes there is an effect.
