Income and housing revisited In Chapter 6, Exercise

32, we learned that the Office of Federal Housing Enter-
prise Oversight (OFHEO) collects data on various as-
pects of housing costs around the United States. Here’s a

scatterplot (by state) of the Housing Cost Index (HCI)
versus the Median Family Income (MFI) for the 50 states.
The correlation is r = 0.65. The mean HCI is 338.2,
with a standard deviation of 116.55. The mean MFI is
$46,234, with a standard deviation of $7072.47.a) Is a regression analysis appropriate? Explain.
b) What is the equation that predicts Housing Cost Index
from median family income?
c) For a state with MFI = +44,993, what would be the
predicted HCI?
d) Washington, DC, has an MFI of $44,993 and an HCI
of 548.02. How far off is the prediction in c) from the
actual HCI?
e) If we standardized both variables, what would be the
regression equation that predicts standardized HCI
from standardized MFI?
f) If we standardized both variables, what would be the
regression equation that predicts standardized MFI
from standardized HCI?
