The 3 year moving averages for the observations 3, 5, 7, 9, 11 are : |
5, 7, 9 3, 7, 11 4, 8, 10 5, 9, 11 |
5, 7, 9 |
The correct answer is Option (1) → 5, 7, 9 $\text{Moving Average} = \frac{\text{Sum of 3 consecutive terms}}{3}$ $⇒\frac{3+5+7}{3}=\frac{15}{3}=5$ $⇒\frac{5+7+9}{3}=\frac{21}{3}=7$ $⇒\frac{7+9+11}{3}=\frac{27}{3}=9$ |
