Answer 1

Verified answer

Materi : Data dan Statistika

Banyak Data = 8 + 11 + 6 + 5 + 2 = 32 data

Jumlah Data

= 8(75) + 11(80) + 6(85) + 5(90) + 2(95)

= 560 + 40 + 800 + 80 + 480 + 30 + 450 + 180 + 10

= 600 + 800 + 500 + 500 + 200 + 30

= 1.400 + 1.000 + 230

= 2.400 + 230

= 2.630

Maka Mean = 2.630/32 = 82,1875

Semoga bisa membantu

Answer 2

MEAN = JUMLAH DATA/BANYAK DATA

= (8 × 75) + (11 × 80) + (6 × 85) + (5 × 90) + (2 × 95)/32

= (600 + 880 + 510 + 450 + 190)/32

= (1.480 + 960 + 190)/32

= (1.480 + 1.150)/32

= 2.630/32

= 82,18
