Archief - ATTN: Studenten steun- en klaagthread - Deel 8

Estrebian zei:

Even een vraag ivm statistiek:
Opgave:
Een MC-examen telt 50 vragen, elk met 4 antwoorden, waarvan er één juist is.

Vraag:
Als een student naar willekeur aankruist, hoe groot is dan de kans op meer dan 20 goede antwoorden?

Oplossing
Bin(50;0.25), dan naar normale verdeling N(12.5;3.06)
P(x>20)= P(y>20.5)= P(Z>(20.5-12.5)/3.06)=P(Z>2.61)=0.0045

Nu vraag ik mij af, waarom gaat men hier van X>20 naar Y>20.5? Dit lijkt mij een opdeling in klassen, maar dit gebeurt toch enkel bij continue variabelen? Volgens mij is het toch een discrete variabele waar men hier mee moet werken?

Je normaalverdeling is continu é, maar je wilt hem wel gebruiken op een discreet iets, en daarom moet je je normaalverdeling opdelen in klassen en dus >20.5 nemen. Allé, denk ik, schiet me niet dood als het mis.
