ATTENTION

The person above is INCORRECT!!!!!!!!!!!!

31.5 IS THE CORRECT ANSWER

Step-by-step explanation:

83, 85, 89, l 91, 95, 104, l 112, 118, 118, l 125, 134, 138

Q₁ = (89 + 91)/2 = 90

Q₂ = (104 + 112)/2 =108

Q₃ = (118 + 125)/2 = 121.5

Interquartile range (IQR) = Q₃ - Q₁

= 121.5 - 90

IQR = 31.5

k12 approved! I had it on my quiz and it is correct.
