tolong dijawab pake cara gua follow​

Answer 1

》Statistika

Rata-rata = Jumlah nilai ÷ Jumlah data

• = 300 ÷ 40
• = 7,5 [ OPSI B ]

Jumlah nilai =

= 6 + 8 + 7 + 7 + 6 + 6 + 6 + 7 + 7 + 8 + 9 + 8 + 7 + 7 + 6 + 7 + 9 + 7 + 7 + 7 + 9 + 6 + 6 + 7 + 8 + 9 + 8 + 7 + 8 + 9 + 9 + 6 + 6 + 10 + 9 + 8 + 8 + 7 + 9 + 9

= 300 => Langsung Jumlahkan

Kalau satu satu bakal panjang jawabannya.

Answer 2

SOAL 1

___________________________________________

Rumus :

Mean = J Data/B Data

J Data = 6 + 8 + 7 + 7 + 6 + 6 + 6 + 7 + 7 + 8 + 9 + 8 + 7 + 7 + 6 + 7 + 9 + 7 + 7 + 7 + 9 + 6 + 6 + 7 + 8 + 9 + 8 + 7 + 8 + 9 + 9 + 6 + 6 + 10 + 9 + 8 + 8 + 7 + 9 + 9 = 300

B Data = 40

___________________________________________ Mean = 300/40

Mean = 3/4

Mean = 75/100

Mean = 7,5
