a) Describe the pattern you see here.
b) Should we try re-expressing either variable to make
this plot straighter? Explain.
5. Models For each of the models listed below, predict y
when x = 2.
a) In ŷ = 1.2 + 0.8x
d) ŷ = 1.2 0S lnx
%3D
b) Vŷ = 1.2 + 0.8x
e) log y = 1.2 + 0.3 log x

6. More models For each of the models listed below,
predict y when x =
2.
%3D
a) ŷ = 1.2 + 0.8 log x
d) ỹ² = 1.2 + 0.8x
b) logŷ = 1.2 + 0.8x
= 1.2 + 0.8x
%3D
(e)
c) In ŷ = 1.2 + 0.8 Inx
7. Gas mileage As the example in the chapter indicates,
one of the important factors determining a car's Fuel
Efficiency is its Weight. Let's examine this relationship
again, for 11 cars.
a) Describe the association between these variables
shown in the scatterplot.
