Answer:

The residual of 1 is 0.5.

Step-by-step explanation:

The given function is

$y=2x+1.5$

Substitute x=1 in the given equation of line, to find the expected or estimated value of the function at x=1.

$y=2(1)+1.5$

$y=3.5$

The point (1, 4) is in the data set. It means the actual value of the function is 4 at x=1.

The formula to calculate the residual is

Residual = Observed value - Estimated value

The residual of 1 is

$Residual=4-3.5=0.5$

Therefore the residual of 1 is 0.5.
