Hipotesa intersep dan slop = Setiap kenaikan jumlah air dalam makanan dan umur mempengaruhi berat jenis urin namun interaksi keduanya tidak mempengaruhi berat jenis urin .

Kesimpulan:
Penambahan variabel X1 dan X2 kedalam
model bermakna karena Parsial F > Ftabel(1), dengan kata lain
perlu menambahkan variabel tersebut kedalam model regresi. Sedangkan variabel
selain itutidak perlu ditambahkan kedalam model regresi sehingga model regresi
akhir adalah sebagai berikut :
Y
= β0 + β1X1 + β2X2
= 48.61271 + 1.02892 Umur + 10.45104 IMT
