Using the trend line y = 2x + 15, for the data shown, complete the residual table.

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

probability for j is 1/4

while

a is 1/6
