Modus = 75,5 + 4/(4+6) × 3
Modus = 75,5 + 12/10
Modus = 75,5 + 1,2
Modus = 76,7 juta
76. C
Tb = 29,5
d1 = d2 = 14–7 = 7
p = 5
Modus = 29,5 + 7/(7+7) × 5
Modus = 29,5 + ½ × 5
Modus = 29,5 + 2,5

d2 = 12–7 = 5
p = 6
Modus = 57,5 + 3/(3+5) × 6
Modus = 57,5 + ⅜ × 6
Modus = 57,5 + 18/8
Modus = 57,5 + 2,25
