Dengan menggunakan penghitungan yang tepat, ubahlah supaya interval yang kalian temukan di nomor 4 menjadi bentuk yang memuat P(0 ≤ z ≤ k) dengan k ∈ R, sehingga bisa disesuaikan dengan tabel distribusi normal.
Contoh :
P(z ≥ 2,54) = P(z ≥ 0) - P(0 ≤ z ≤ 2,54)
↔ P(z ≥ 2,54) = 0,5 - P(0 ≤ z ≤ 2,54)

Berdasarkan penjabaran yang dikerjakan pada soal nomor 6, tentukan nilai probabilitas interval yang ditentukan pada soal nomor 2 (dengan bantuan tabel)
Contoh :
P(z ≥ 2,54) = 0,5 - P(0 ≤ z ≤ 2,54)
↔ P(z ≥ 2,54) = 0,5 - 0,4945
↔ P(z ≥ 2,54) = 0,0055
