  5. TWIN wiskundeStatistiek en kans m = gemiddelde s = standaard afwijking de normale verdeling modus, mediaan, gemiddelde vallen samen grafiek symmetrisch oppervlakte 100% van m-3s tot m+3s 68 % 95 % 100 %

  6. TWIN wiskundeStatistiek en kans -2 -1 0 1 2 de standaard normale verdeling stap 1: -m stap 2: :s met de tabel: Ф(z) = …... Ф(1) = 0,8413 = 84,13 %

  7. TWIN wiskundeStatistiek en kans -2 -1 0 1 2 de standaard normale verdeling DISTR (2nd VARS) 2:normalcdf( normalcdf(-1E99,1.00) met de GRM: Ф(z) = …... Ф(1) = 0,8413 = 84,13 %

  8. TWIN wiskundeStatistiek en kans de standaard normale verdeling tekenscherm schoonmaken met DRAW (2nd PRGR) 1:ClrDraw

  9. TWIN wiskundeStatistiek en kans de standaard normale verdeling DISTR (2nd VARS) DRAW 1:ShadeNorm( ShadeNorm(-1E99,1.00) met de GRM: Ф(z) = …... Ф(1) = 0,8413 = 84,13 %

  10. TWIN wiskundeStatistiek en kans de standaard normale verdeling nu anderom: Ф(z) = 0,6543 = 65,43 % z=? Y= Y1=normalcdf(-1E99,X) Y2=0.6543
