Bisa jawab nomer 3 sama 4 gak? Plisss
Jawab:
3. banyak pedagang = 600 x 30% = 600 x 30/100 = 6 x 30 = 180
4. Median berada pada kelas inetrval (60 – 69)
interval = 10
Jumlah Fk = 8 +10 = 18
f = 14
N = 40/2 = 20
tepi atas = (60 + 59) /2 = 119/2 = 29,5
Me= 29,5 +[20-10/14] 18
Me = 29,5 + [10/14]18
=29,5 + 90/7
= 29,5 + 12,86
= 42,36
