De berekening en de conclusie is correct. Er mocht wel iets meer informatie bij.

We zien duidelijk dat de mediaan van de gegevens van de investeringen het laagst is. De inkepingen van de drie eerste kolommen gegevens overlappen elkaar nog terwijl dat niet het geval is bij de investeringen. De hypothese is dus correct.

Het antwoord was correct. Visueel kan je op basis van de mediaan vaststellen dat de investeringen het meeste verval hebben gekend. Maar je kan dit ook vaststellen aan de hand van de lower en upper bound. Voor investeringen zien we dat de lower en upper bound (48.5928905074159 en 60.4071094925841) nergens overlappen met de andere lower and upper bounds. We kunnen dus stellen dat het verschil hier significant is.
