Mencari frequensi harapan n(s) = 6 jawabn soal a n(a) = 4= 1 Fh = n(a)/n(s) x banyak pelemparan = 1/6 x 10 = 5/3 jawabn soal b n(a) = ( 2,4,6) = 3 Fh = 3/6 x 10 = 5 jawaban soal c n(a) = (1,2,3,4,5) = 5 Fh = 5/6 x 10 = 25/3
n(s) = 6
jawabn soal a
n(a) = 4= 1
Fh = n(a)/n(s) x banyak pelemparan
= 1/6 x 10
= 5/3
jawabn soal b
n(a) = ( 2,4,6)
= 3
Fh = 3/6 x 10
= 5
jawaban soal c
n(a) = (1,2,3,4,5)
= 5
Fh = 5/6 x 10
= 25/3
