Answer:
The correct option is A.
Step-by-step explanation:
From the given information it is clear that at x=25, the predicted value of y is 27.745 and the actually value is 29.
Predicted value = 27.745
Observed value = 29
The formula for residual is
Residual = Observed value - predicted value



The residual in this case is 1.255, therefore option A is correct.
