Answer:
The residual e=2 when x = 5.
Step-by-step explanation:
A scatter plot containing the point (5, 29), it means the observed value at x=5 it 29.
The given regression equation is
[tex]\hat{y}=5x+2[/tex]
Substitute x=5 in the above regression equation, to find the predicted value at x=-5.
[tex]\hat{y}=5(5)+2=25+2=27[/tex]
The formula to find the residual value e is
e = Observed value - Predicted value
[tex]e=29-27[/tex]
[tex]e=2[/tex]
Therefore the residual e=2 when x = 5.
