Given a data set with 3 points, and 2 residuals of -12 and 6, find the third residual.

STEP 1

Assumptions1. The data set contains three points. . Two of the residuals are -12 and6.
3. The sum of residuals in a data set is always zero.

STEP 2

The sum of residuals is always zero, so we can set up the following equation to find the third residual12+6+x=0-12 +6 + x =0where x is the third residual.

STEP 3

olve the equation for x.
x=126=6x =12 -6 =6The third residual is6.
So, the correct answer is A.6.
