Ik had geen antwoord gegeven, omdat ik dacht dat je een antwoord moest geven bij elk streepje (-) apart.

Als we nu een lijn zouden trekken ter hoogte van 103,8, kunnen we besluiten dat IND10_UT90 de beste investering is. De lijn ligt hier namelijk onder het betrouwbaarheidsinterval van IND10_UT90. IND30_UT70 is een randgeval.

Astrid maakt hier opnieuw een correcte reproductie, maar ze geeft geen antwoord op de vraag. Aan de hand van haar eigen beoordeling, kunnen we nu ook weer stellen dat ze vraag heeft begrepen.

Bij de laatste boxplot (IND10_UT90) zien dat de mediaan het hoogst is. In de opgave kunnen we lezen dat de investeerder een rendement wilt dat hoger ligt dan 3,8%. Kijken we opnieuw naar de laatste boxplot, dan kunnen we stellen dat de mediaan hier hoger ligt.

Als we kijken naar de lower bound, zien we dat de laatste boxplot (IND10_UT90) de hoogste waarde vertoont in vergelijking met de andere 4. Hier wordt ook nog eens aangetoond dat het rendement hoger dan 3,8% ligt.

Inderdaad een correcte berekening, maar geen antwoord op de vraag.
De beste investering is de Ind10_Ut90 (helemaal de rechtse).
Die heeft de kleinste spreiding en de hoogste mediaan.
De laatste boxplot is dus de beste.
De vraag is hier dus blijkbaar niet begrepen en student heeft daardoor dan ook geen antwoord gegeven.
