C Table 2 de la loi Normale centrée réduite

\(X\) étant une variable aléatoire de loi \(\mathcal{N}(0,1)\) et \(\alpha\) un réel de \([0,1]\), la table donne la valeur de \(z_{1-\frac{\alpha}{2}}=\Phi^{-1}(1-\frac{\alpha}{2})\) telle que \(P(|X| > z_{1-\frac{\alpha}{2}})=\alpha\). En , la commande correspondante est qnorm(1-alpha/2).
