H0: d  d0 H0: d ≥ d0

H1: d > d0 H1: d < d0

b. Hipotesis Dwi Arah

H0: d = d0

H1: d  d0

• Statistik Uji:

a. Ragam diketahui:

Zhit = d − d 0  Normal(0,1)
 d / n

b. Ragam tidak diketahui

d − d
Thit = 0  t(db=n-1)
s / n
d

• Kriteria penolakan H0

o H0: d  d0
Tolak H0 jika thit > t(db=n-1)

H1: d > d0

o H0: d ≥ d0 Tolak H0 jika thit < t1-(db=n-1)

H1: d < d0

o H0: d = d0 Tolak H0 jika |thit| > t/2(db=n-1)

H1: d  d0
