Langkah Pembuktian Hipotesa
54
A.asumsi :bahwa model persamaan garis lurus beserta asumsinya berlaku ;
55
B. Hipotesa : Ho:

58
C. Uji statistik :

60
61
D. Distribusi statistik : bila asumsi terpenuhi dan Ho diterima maka uji t digunakan dengan derajat kebebasan n-1
62
E.Pengambilan keputusan : Ho ditolak bila nilai
lebih besar dari
63
f. Perhitungan statistik : dari komputer out put diperoleh besaran nilai

67
G.Keputusan statistik :
Nilai thitung = 4.036 > t tabel =2.055553
68
Kita menolak hipotesa Nol
69
H. Kesimpulan : Slop garis regresi tidak sama dengan 0 maka garis regresi antara IMT dan GPP adalah linier
