For the given 5 values, 35, 70, 30, 62, 58, the 3-year moving averages are
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → 45, 54, 50
Each 3-year moving average is the mean of three consecutive values:
\( \displaystyle \frac{35+70+30}{3}=45 \)
\( \displaystyle \frac{70+30+62}{3}=54 \)
\( \displaystyle \frac{30+62+58}{3}=50 \)
