Bonjour! 😉

je ne suis pas d'accord avec les corrections de ce post

Par rapport à l'item E, on nous dit que la P(PAS>140)<2,5%

Et dans les corrections, on utilise les seuils de la loi normal pour un test bilatérale,

sauf que pour un test unilatérale, P(X>mu+moins de 2 sigma)<5%

Vous en pensez quoi? 😕

Merci
