For the given five values 13, 24, 17, 31, 45, the three years moving averages are. |
18, 21, 33 18, 24, 31 15, 27, 31 17, 24, 32 |
18, 24, 31 |
The correct answer is Option (2) → 18, 24, 31 $\text{Data: } 13, 24, 17, 31, 45$ $\text{First average} = \frac{13+24+17}{3} = \frac{54}{3} = 18$ $\text{Second average} = \frac{24+17+31}{3} = \frac{72}{3} = 24$ $\text{Third average} = \frac{17+31+45}{3} = \frac{93}{3} = 31$ The three-year moving averages are $18, 24, 31$. |
