For the given five values, 3.6, 4.3, 4.3, 3.4, 4.4, the three years moving averages are:
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → 4.067, 4.00, 4.03
Given data: 3.6, 4.3, 4.3, 3.4, 4.4
Three-year moving averages:
First 3-year average: $\frac{3.6 + 4.3 + 4.3}{3} = \frac{12.2}{3} \approx 4.067$
Second 3-year average: $\frac{4.3 + 4.3 + 3.4}{3} = \frac{12.0}{3} = 4.0$
Third 3-year average: $\frac{4.3 + 3.4 + 4.4}{3} = \frac{12.1}{3} \approx 4.033$
