For the given five values, 3.6, 4.3, 4.3, 3.4, 4.4, the three years moving averages are: |
12.2, 12.0, 12.1 4.00, 4.03, 4.40 12.0, 12.1, 13.2 4.067, 4.00, 4.03 |
4.067, 4.00, 4.03 |
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: $\frac{4.3 + 3.4 + 4.4}{3} = \frac{12.1}{3} \approx 4.033$ |
