De vraag werd correct beantwoord. IND10_UT90 is de beste inverstering. De medianen van de andere schommelen allemaal rond 103, enkel deze ligt erboven.

Het antwoord van de student is correct.

IND10_UT90 is inderdaad de beste inverstering die men kan doen. Dit 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%. Als we terug naar de laatste boxplot kijken, dan kunnen we zien dat de mediaan van IND10_90 ook boven deze waarde ligt (103,8). 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. Hierdoor kunnen we dus effectief vaststellen dat deze dan ook de beste investering is.
