Hipotesis Statistik
Ho: ρxy = 0 (Tidak terdapat hubungan antara tinggi badan dan berat badan) H1: ρxy ≠ 0 (Terdapat hubungan antara tinggi badan dan berat badan)
Dari tabel t dengan α = 0,05 Diperoleh ttab = t0.025;df=8 = 2,306 Kriteria uji: Karena
( ) α = 0,025 dan df = n-2
df = 10 – 2 = 8
= 8,295> ttab = 2,306 maka Ho ditolak
Kesimpulan: “Bahwa Berat Badan Berpengaruh Signifikan Terhadap Berat Badan”.
