Use the following information for questions:
The data from a representative sample of 43 male college students was used to determine a regression equation for y = weight (lbs) and x = height (inches). The least squares regression equation was $\hat{y}$ = -318 + 7.00 x. The error sum of squares (SSE) was 23617; the total sum of squares (SSTO) = 34894.
-For a male student with a height of 70 inches and a weight of 200 lbs, what is the value of the residual?
A) -28
B) 28
C) 172
D) 200

Quizplus · Accepted Answer

The predicted weight for a height of 70 inches is $\hat{y} = -318 + 7.00 \times 70 = 172$ lbs. The residual is the actual weight minus the predicted weight: $200 - 172 = 28$.
