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 Indexfrom median family income?c) For a state with MFI = +44,993, what would be thepredicted HCI?d) Washington, DC, has an MFI of $44,993 and an HCIof 548.02.
