Tolong jawab nomor 9

Statistik


Rata-rata = (3,0 x 4) + (3,2 x 7) + (3,3 x 1) + (3,4 x 2) + (3,5 x 1)
                   -----------------------------------------------------------------
                                           4 + 7 + 1 + 2 + 1

Rata-rata = 12 + 22,4 + 3,3 + 6,8 + 3,5
                   ---------------------------------
                                   15

Rata-rata = 48/15
                = 3,2

Data diatas rata-rata
= (3,3) (3,4) (3,5)


Maka, jeruk bali yang beratnya diatas rata-rata sebanyak 4 buah (B)
