Je hebt voor het oplossen van vraag 2 uit workshop 1 part 1, gebruik gemaakt van de Testing Mean (unknown Variance) - p-value (new) test. In de les hebben we gebruik gemaakt van Testing Mean with unknown Variance - Critical Value. Probeer deze berekening eens, dan ga je wel de juiste oplossing vinden en kan je vervolgens een interpretatie geven aan je gegevens. Je gaat dan kijken naar het betrouwbaarheidsinterval. Je kan ook via de p-waarde werken, maar ik weet niet zeker of jou berekening dan klopt. Als je uw p-waarde bekijkt, moet je de nulhypothese accepteren en dat doe je ook als je naar het betrouwbaarheidsinterval kijkt. Ik werk persoonlijk liever met het betrouwbaarheidsinterval.

Deze opmerking geldt voor alle hypotheses die je teste in vraag 2.
