Question: 29. Consider the following data set. X 6 8 11 15 17 20 25 30 33 40 Y 20 23 32 38 40 44 39

29. Consider the following data set.

X 6 8 11 15 17 20 25 30 33 40 Y 20 23 32 38 40 44 39 32 26 24

(a) Fit these data to the following models:

Yi = β0 + β1Xi + εi, i= 1, . . . , 10 Yi = τ0 + τ1Xi + τ2X2 i + εi, i= 1, . . . , 10

(b) Perform residual analysis for both fits and conclude which is a better one.
