Uji - F

(JKreg a) = (ΣY)²/n =

b = n.ΣXY-ΣX.ΣY/n.ΣX²-(ΣX)² =

0,119885

[Jkreg a(b/a)] = b[ΣXY -( ΣX.ΣY/n)]  =

0,740768

Jkres = ΣY² - {Jkreg a(b/a) + Jkreg(a)} =

0,640931

RJKreg (a) = JKreg (a)   =

RJKreg(b/a) = Jkreg (b/a)  =

0,740768

RJKres = Jkres/n-2  =

0,045781

Fhitung = RJKreg(b/a)/RJKres  =

16,18077

Ftabel = F(a)(1,n-2) =

3,63

Jadi, Fhitung > Ftabel ; Ho ; Ditolak artinya ; Model Regresi linear sederhana dapat digunakan

konstanta a ;

α = ΣY-b.ΣX/n =

95,06337

Persamaa Regresi Linear Sederhana ;

Y = α + b.X =

r  =  n(ΣXY)-(ΣX.ΣY)/√[n.ΣX²-(ΣX)²][n.ΣY²-(ΣY)²]   =

Strong Correlation's

t-hitung  =  r√n-2/√1-(r)²  =

4,022533

t-tabel = 2,12

n = 16

Jadi, t-hitung > t-tabel ; Ho ; Ditolak artinya ; Tingkat Durasi Iklan Sangat Berpengaruh terhadap Banyak Penjualan
