Interval Kepercayaan (Confidence Interval) Interval kepercayaan adalah suatu penduga yang diyakini untuk suatu distribusi probabilitas dalam taraf nyata yang kemudian dinotasikan dengan α (alpha) yang selalu dinyatakan dengan presentase. Apabila suatu kurva normal dengan α= 5% (ditulis α= 0,05) ,maka sisis dari kurva normal akan terlihat sebagai berikut: untuk uji satu sisi untuk uji dua sisi Penduga nilai-nilai estimasi ini sangat tergantung pada total sampelnya . 1) Apabila n ≥ 30 , untuk menghitung interval kepercayaannya kita menggunakan distribusi normal .
