A. The 3-year moving average from 2002 to 2004 is 4.00

B. The 3-year moving average from 2005 to 2007 is 3.73

C. The 5-year moving average from 2001 to 2005 is 4.00

D. The 5-year moving average from 2004 to 2008 is 3.83

E. The 4-year moving average from 2001 to 2004 is 3.90

Choose the correct answer from the options given below :

A, C, E only

The correct answer is Option (1) → A, C, E only

$\text{3 years moving average}=\frac{\text{Sum of 3 consecutive year}}{3}$

(A) $\frac{4.3+4.3+3.4}{3}=\frac{12.0}{3}=4.00$

(C) $\frac{3.6+4.3+4.3+3.4+4.4}{5}=\frac{20.0}{5}=4.00$

(E) 4 Year moving average,

$\frac{3.6+4.3+4.3+3.4}{4}=\frac{15.6}{4}=3.90$
