Suppose the average size of a new house built in a certain
county in 2006 was
2,271
square feet. A random sample of
30
new homes built in this county was selected in 2010. The average
square footage was
2,187,
with a sample standard deviation of
220
square feet.
a.
Using
alphaαequals=0.10,
does this sample provide enough evidence to conclude that the
average house size of a new home in the county has changed since
2006?
b.

1)A real estate agent
is interested in determining factors that affect the mean selling
price of a home. One factor she is considering is known as "lot
configuration," which determines the position of the house within
the neighborhood that it is built. The possible lot configurations
are (don't worry about their precise definitions):
Inside: Inside
lot
Corner: Corner
lot
CulDSac Cul-de-sac
FR2: Frontage
on 2 sides of property
FR3: Frontage
on 3 sides of property
Suppose that she were
to perform an ANOVA to examine...
