Question

In real estate, it is common knowledge that where the house is located is extremely important (many people summarize this by saying the three most important factors in home sales are location, location, and location). Many characteristics of a house are tied to its location, one of which is age. Some neighborhoods are considered "old" while others are considered "new," with new homes generally selling at a higher price.

One way to compare "old" and "new" neighborhoods is to examine the difference in the mean age of houses in those neighborhoods. Ben, a real estate agent, is interested in determining whether the mean age of houses located in the Peaceful Pines neighborhood (Group 1) differs from the mean age of houses in the Whispering Willows neighborhood (Group 2). To examine this question, he will perform a hypothesis test using a sample of six houses from each neighborhood. The data (representing the ages in years of each home) are as shown below:

**Peaceful Pines**

21, 43, 55, 51, 53, 52

**Whispering** **Willows**

45, 36, 42, 53, 47, 46

Calculate the test statistic for the hypothesis test that Ben
would be interested in conducting, to two decimal places.
**Use Case 2 (assuming unequal population standard
deviations). Inputting the data into Excel will make the
calculations much easier.**

Part A – EVC Analysis
A homeowner has asked a local real estate agent for advice on
the price he should set for his house. The real estate agent notes
that the only comparable house in the neighborhood that is
currently for sale is asking $350,000. Both houses are on a hill
that overlooks a beautiful lake, but the owner’s house is forty
feet farther up the hill than the comparable house. The agent
estimates that, in this area, customers...

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...

1.A real estate analyst has developed a multiple regression
line, y = 60 + 0.068 x1 – 2.5
x2, to predict y = the market
price of a home (in $1,000s), using two independent variables,
x1 = the total number of square feet of living
space, and x2 = the age of the house in years.
With this regression model, the predicted price of a 10-year old
home with 2,500 square feet of living area is __________.
$205.00
$255,000.00
$200,000.00...
