De student heeft voor deze vraag gebruik gemaakt van de juiste methode namelijk de Univariate Explorative Data Analysis . De grafiek van de verhouding tussen de kledingproductie en de totale productie vertoont een dalende trend; in tegenstelling tot de grafiek van de kledingproductie die een dalende trend vertoont in de eerste 2,5 jaar , dan een dieptepunt bereikt en zich vanaf dan stabiliseert. De reeksen volgen dus niet dezelfde trend.

Er is inderdaad de juiste berekening gemaakt en de kledingproductie daalt ten opzichte van de totale productie.
Je ziet duidelijk op de grafiek (run sequence plot) dat het eerste deel daalt en daarna constant blijft.

De berekening die de student maakt is volledig correct.
Het klopt inderdaad dat de kledingproductie afwijkt van de totale productie.
Dit kan men bewijzen door aan te tonen dat c niet constant is maar een dalend verloop kent.
