Indien we een betrouwheidsinterval willen creëren van 95%, zullen we aan beide staarten van de resultaten 2,5% moeten laten wegvallen.

Eerst zoeken we het max. en min. interval, in dit geval, 0.70606 en 1.04239 daarna moeten we deze resultaten verminderen met het gemiddelde van de tekenreeks (0,8621).

Hierna bekomen we 0,15603 en 0,18029.

De student heeft verwezen naar de oplossing van de student maar je kan dit resultaat ook bekomen op een andere manier

Manier 2:
Ja kan de R-code veranderen door bovenaan x door ‘x <- x –gemiddelde’ toe te voegen

Het voordeel van deze methode is dat je achteraf geen berekeningen meer moet gaan uitvoeren zoals bij de eerste methode.
