JAWABAN UAS STATISTIKA SOSIAL 2019

TABEL PENOLONG !
no. tahun BI Rate (Y) Inflasi (X) XY X² Y²
1 2003 8.3 5.1 42.33 26.01 68.89
2 2004 7.4 6.4 47.36 40.96 54.76

10 2012 4.8 4.3 20.64 18.49 23.04
11 2013 7.2 8.4 60.48 70.56 51.84
12 2014 6.9 8.4 57.96 70.56 47.61
13 2015 7.1 3.4 24.14 11.56 50.41
14 2016 5.9 3 17.7 9 34.81
Σ (SUM) = 107.1 94 810.25 821.16 882.69
UJI -F (LILIE FORCE) ; UJI LINEARITAS ;
(Jkreg α) = (ΣY)²/n = 819.315 JUMLAH KUADRAT REGRESI A
b =( n.ΣXY-ΣX.ΣY)/n.ΣX²-(ΣX)² = 0.479694
α = (ΣY - b.ΣX)/n = 4.4292
[Jkregα(b/α)] = b.((ΣXY -(ΣX.ΣY)/n)  43.72407
Jkres = ΣY² - {Jkregα(b/α) + Jkreg(α)} = 19.65093
RJKreg(α) = Jkreg(α) = 819.315 RATA-RATA JUMLAH KUADRAT REGRESI
RJKreg(b/α) = Jkreg(b/α) = 43.72407
RJKres = Jkres / n-2 =  1.637578
F-hitung = RJKreg(b/α) / RJKres = 26.70046
F-tabel(1-5%) (1,n-2) lihat tabel uji-f
F-tabel (0.95)(1,14-2) atau F(0.95)(1,12) = 3.885
Jadi, F-hitung > F-tabel = 26.70046 > 3.885 ; maka, Ho ditolak ; sehingga regresi linear sederhana dapat digunakan untuk mempredikti tingkat inflasi terhadap BI Rate
bisa juga, data tersebut bersifat linear
Regresi Linear Sederhana ; Y = α + bX = Y = 4.4292 + 0.479694X ; Persamaan regresi linear sederhana
statistika parametrik (uji-t/t-test) ;
r = (n(ΣXY)-(ΣX.ΣY))/((√(n.ΣX²-(ΣX)²)(n.ΣY²-(ΣY)²)) =  1276.1 2660.24 887.25 0.830618 ; Korelasi bersifat Superior, yaitu berkisar 0.76 sampai 0.99
1536.326
hypothesis : Ho : Tidak terdapat pengaruh besar (signifikan) kenaikat tingkat suku bunga terhadap laju inflasi di indonesia.
                  Ha : terdapat pengaruh besar kenaikan tingkat suku bunga BI terhadap laju inflasi di indonesia.
t-hitung = r√n-2/√1-(r)² =
5.167248


t-tabel (α/2)(n-2) = t(0.05/2)(14-2) =  2.179
Lihat tabel uji-t ; t(0,025)(12)
Jadi, t-hitung > t-tabel = 5.167248 > 2.179 ; maka, Ho tolak ; sehingga terdapat pengaruh besar (signifikan) antara tingkat suku bunga BI terhadap Inflasi di Indonesia sejak tahun 2003 sampai 2016
