The production (in thousand tonnes) of a plant from 2017 to 2021 was 84, 94, 120, 154, 88. What was the average yearly production?
Answer and explanation
Correct answer: A. 108
- Step 1: Total = 84 + 94 + 120 + 154 + 88 = 540. Step 2. Average = 540 ÷ 5 = 108. Answer: 108. Why not the others: 94 is what you get if you give the median. 540 is what you get if you forget to divide by 5. 70 is what you get if you give the range.
