De student heeft hier een verkeerde methode gebruikt. De student had hier 3 verschillende hypothesis tests (t-distribution) moeten maken. Zo zou de student voor het de tweede test komen op volgende oplossing: de nulhypothese moet verworpen worden want de nulhypothese (= 0) ligt niet in het betrouwbaarheidsinterval [0.340093327772767 , 0.688478100798662].
