Persamaan garis
                GPP = 48.737 + 4.319 IMT
-          Derajat kebebasan n-2 = 25
-          Nilai t table 2.059
-          = 4.319, S= 1.070
-          Nilai t=
-          Niali t hitung 4.036 > nilai t table 2.059
-          Hipotesa ditolak
-          Kesimpulan: Slop garis regresi tidak sama dengan 0 maka garis regresi antara IMT dan GPP adalah linier
