Given:
The data table is given.
The equation of trend line is:

To find:
Values for residual table.
Solution:
Formula for residual:

The equation of trend line is:
...(i)
Substituting
in (i), we get



The value of y from the table at
is 25. So,


Similarly,
Substituting
in (i), we get



The value of y from the table at
is 28. So,


Substituting
in (i), we get



The value of y from the table at
is 29. So,


Substituting
in (i), we get



The value of y from the table at
is 30. So,


Substituting
in (i), we get



The value of y from the table at
is 32. So,


Therefore, the complete residual table is:
x : 5 6 7 8 9
Residuals : 0 1 0 -1 -1
