Het antwoord van de student is helemaal correct. Er kan nog aan toegevoegd worden dat de meting geen toeval is: de notches of inkepingen bepalen eigelijk de grenzen van het betrouwbaarheidsinterval. Daartussen kan de mediaan verschuiven maar voor 95% is het zeker dat die tussen de lijnen liggen van de notches (= een horizontale lijn trekken van de beginpunten van de notches naar de y-as). Hieruit kunnen we dan de conclusie trekken dat deze lijnen nog duidelijk onder het betrouwbaarheidsinterval van de totale productie liggen. De mediaan van de de kledingproductie is dus significant kleiner dan die van de totale productie.

We kunnen hier stellen dat de mediaan van de kleding productie significant of beduidend lager ligt dan deze van de totale productie. Als we het betrouwbaarheidsinterval van de kleding productie doortrekken naar links toe, kan je zien dat deze lager blijft dan die van de totale productie dit wijst op een significante daling
