The production (in thousand tonnes) of a plant from 2020 to 2024 was 143, 102, 92, 193, 190. What was the average yearly production?
Answer and explanation
Correct answer: C. 144
- Step 1: Total = 143 + 102 + 92 + 193 + 190 = 720. Step 2. Average = 720 ÷ 5 = 144. Answer: 144. Why not the others: 143 is what you get if you give the median. 720 is what you get if you forget to divide by 5. 101 is what you get if you give the range.
