Ik denk dat ik deze berekening juist heb uitgevoerd.

Het enige correcte anwoord is IND10_UT90(IND30_UT70 kan eventueel ook maar IND10_UT90 is beter, dit wordt nog verder uitgelegd). De beste investering die men kan doen kunnen we ten eerste afleiden uit de Notched box plot grafiek. De mediaan van deze investering ligt het hoogtst t.o.v. de andere 4. Maar dit zou niet voldoende zijn.

In de opgave staat ook dat de investeerder een rendement wil dat hoger ligt dan 3,8%(103,8).
Als we terug naar de laatste boxplot kijken, dan kunnen we zien dat de mediaan van IND10_90 boven deze waarde ligt. In de tabel zie je de exacte waarde van de lower bound van IND10_UT90, deze bedraagt 104,388 en ligt beduidend hoger dan de lower bound van de drie andere investeringen. De lowerbound van IND30_UT70 bedraagt juist 103,8 wat dus ook nog aan de vooropgestelde waarde van 3,8% voldoet. Maar omdat die van IND10_90 hoger ligt verkiezen we uiteindelijk toch dat deze de beste investering is.

We gaan de notched box plot gebruiken, hieruit kunnen we de beste investering afleiden, namelijk IND10_UT90. Bij deze investering ligt de mediaan op de grafiek hoger dan bij de andere. De investeerder kiest de investering die het beste rendement oplevert, en dit moet minstens 3,8% zijn of hoger. We kijken naar de boxplot=>hier zien we dat het mediaan van IND10_UT90 boven de 3,8% ligt. De lower bound vinden we in de tabel, bij IND10_UT90 is dit 104,388 ( en dit is hoger dan de lower bound van de andere investeringen) Als we nu rekening houden met die 3,8% dan komen we uit bij IND30_UT70, want deze is juist 103,8 (en voldoet aan de voorwaarde) Maar uiteraard wil de investeerder een rendenment van 103,8 en liefst hoger dus nemen we IND10_UT90 want hier ligt het rendement hoger en zal dus beter zijn voor de investeerder.
