Hipotesis untuk kasus ini :H1 = > 100 ( ada perbedaan IQ antara nilai data sekarang dengan nilai data yang lalu )H0 = 100 ( tidak ada perbedaan IQ antara nilai data sekarang dengan nilai data yang lalu)Kriteria / Pengambilan Keputusan: H0 ditolak jika p < , = 0,05H0 diterima jika p > , = 0,05Hasil uji statistik :t = 5.270 ; df 39 ; p = 0,000Kesimpulan :karena p = 0,000 < , = 0,05 maka H0 ditolak.InterpolasiDengan taraf kepercayaan 95% hasil pengujian mendukung hipotesis yang menyatakan bahwa IQ mahasiswa sekarang lebih besar dari data IQ mahasiswa yang lalu.
