Suatu penelitian ingin
menyelidiki hasil biakan kuman yang terdiri dari 4 strain. Uji strain I, II,
III, III, IV. Sampel diambil dari para pekerja yang terluka, kemudian dibiakkan
pada pembenihan A, B, C. Apakah ada perbedaan distribusi train kuman Stapilococcus hasil biakkan ketiga
pembenihan?

Kesimpulan
H0: tidak ada
perbedaan antara strain dengan media pembenihan.
H1: ada
perbedaan antara strain dengan media pembenihan.
p-value = 0.017
lebih kecil dari α = 0.05 (p-value < α)
H0 ditolak : ada
perbedaan antara strain dengan media pembenihan.

**. Correlation is significant at the 0.01 level (2-tailed). |
·
H0 = Tidak ada korelasi
antara pengetahuan dan sikap
·
H1 = Ada korelasi antara
pengetahuan dan sikap
·
α = 0,05
·
p-value = 0,00
·
p-value<α
·
H0 ditolak, Ada korelasi
antara pengetahuan dan sikap
·
P value 0,000 < α
(0,05), maka hasilnya signifikan.
Kesimpulan :
Jadi, H0 ditolak
sehingga ada korelasi antara nilai pengetahuan
dan sikap
