Ciri-ciri distribusi normal ,[object Object],[object Object],[object Object],[object Object],[object Object]

DISTRIBUSI NORMAL ,[object Object],[object Object],[object Object],[object Object],[object Object]

Kurva normal Gambar 6.1 Kurva normal

Gambar 6.1 Kurva normal dengan simpangan baku sama

Gambar 6.3 Kurva normal dengan rata-rata sama

Gambar 6.4 Kurva normal dengan mean dan standart deviasi yang berbeda

[object Object],[object Object],[object Object],[object Object],[object Object]

Luas daerah dibawah kurva normal Luas daerah kurva normal antara x = a dan x = b dinyatakan sbb: a b Gambar 6.5 Luas daerah P(a<x<b) = luas daerah di arsir

Untuk mengatasi kesulitan menghitung integral ,[object Object],[object Object],x = nilai variable random µ = rata-rata distribusi σ = simpang baku Z = nilai standar, yaitu besarnya penyimpangan suatu nilai terhadap rata-rata yang dinyatakan dari unit SD.

Contoh soal ,[object Object],[object Object],[object Object],[object Object],Gunakan tabel distribusi normal standart, diperoleh:

Contoh soal ,[object Object],z 0.00 ……… 0.04 …… .. 0.09 : : -0.5 0.3085 0 : : 1.2 0.8849 : :
