Als we het betrouwbaarheidsinterval (de inkepingen) van de investeringen vergelijken met de andere boxplots, komen we tot de conclusie dat de investeringen het meeste verval gekend hebben en dit gaat om een significante daling.
We kijken niet naar de spreiding vermits deze niets te maken heeft met de boxplots. We bestuderen eerder de mediaan (bij de investeringen ligt die ook het laagst). Hetzelfde kan gezegd worden over de lower- en upper bound (ook het laagst).
De hypothese in de vraagstelling klopt, maar dit vind ik niet terug in het document van de student.
