A cat breeder is interested in what specific attributes people
like most about cats. Specifically, they are interested to see
whether the gender and color (black, white, orange, or other) have
a significant impact on the popularity of the cat. The predictor
variables are defined as follows:
?1={10if femaleif male,?2={10if blackotherwise,?3={10if
whiteotherwise,?4={10if orangeotherwisex1={1if female0if
male,x2={1if black0otherwise,x3={1if white0otherwise,x4={1if
orange0otherwise
A regression model was fit and produced the following
results:
?̂

a) What is the estimated popularity for an orange female
cat?
?̂ =y^=
b) What is the estimated popularity for a black male cat?
?̂ =y^=
c) Is a calico cat more popular as a female or male?
Female calico: ?̂ =y^=
Male calico: ?̂ =y^=
Which is more popular?
a)
estimated popularity for an orange female cat =24.05+5.65+6.41 =36.11
b)
estimated popularity for a black male cat =24.05-2.96 =21.09
c)
Female calico (other color) =24.05+5.65 =29.7
Male calico: =24.05
Which is more popular : Female Calico is more populat
