This question was created from 2016S_Bsol.pdf https://www.coursehero.com/file/33832637/2016S-Bsolpdf/

for this question , i dont know where to get SSx and, the next step it says s^2=MSE(1+1/n+...) , however in other past exam there is no one like . s^2 =MSE(1/n+...)

(g) (5 points) What brain weight would you predict for a subject who has a head size of 3100?
Give an appropriate 95% Interval estimate for this prediction as well.
Solution: Yo = 325.57342 + 0.26343(3100) = 1142.204

SS. = 31485993
