Het heeft geen zin om dit te berekenen voor de mannen omdat H0=sample variance.

Dit hoefde niet berekend te worden, omdat de berekening triviaal is, wat wil zeggen dat H0 = sample variance. De grootte van de populatie is de grootte van de steekproef. Bovendien is er geen berekening te zien bij de geblogde link en begrijp ik niet hoe de student de oplossing heeft kunnen concluderen op basis van de geblogde link.
