the equation of the straight line trend is $y = 45.143 + 1.036(x-2003)$, then the trend value for the year 2004 is
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → 46.18 **
Given trend equation:
$y = 45.143 + 1.036(x - 2003)$
For year 2004:
$x - 2003 = 1$
So,
$y = 45.143 + 1.036(1)$
$y = 45.143 + 1.036$
$y = 46.179$
The trend value for the year 2004 is 46.179.
