Setelahdilakukanpengambilansampelsebanyak 20 rumahtanggadidapatkan data sebagaiberikut: 5, 4, 4, 3, 6, 4, 2, 4, 3, 7, 9, 5, 6, 3, 8, 6, 4, 8, 9, 3. akandiujuapakah data resebutberasaldaridistribusi normal atautidak.

  3. Jawab: • Ho: Data berasalpopulasi yang berdistribusitidak normal • H1: Data berasaldaripopulasi yang berdistribusi normal • α=5% • Tabelperhitungan: • = 5,15 • Tob =

  4. Setelahmemasukkanangka-angka yang adakedalamperhitunganmakadiperoleh • Tob = 0,92 • T alfa = 0,905 • KarenanilaiToblebihbesardari T alfa, makakeputusannyaadalahtolak Ho • Kesimpulan : Dengantingkatkepercayaan 95% dipercayabahwasampeldiambildaripopulasi yang berdistribusi normal.
