Bonjour je ne comprends pas la correction de l’item D du QCM 7, est ce que quelqu’un peut m’expliquer pourquoi on prend alpha= 0,01 alors qu’on nous dit que c’est au risque d’erreur de 5% ?

La correction c’est : D. On a ici a = 0,01 et pValue = 0,007.On voit bien que pValue < alpha, on peut donc rejeter l'hypothèse nulle au risque alpha.

Merci !!
