2. Data were collected from a random sample of 220 home sales from a community in 2003. Let Price denote the selling price (in $1000), BDR denote the number of bedrooms, Bath denote the number of bathrooms, Hsize denote the size of the house (in square feet), Lsize denote the lot size (in square feet), Age denote the age of the house (in years), and Poor denote a binary variable that is equal to 1 if the condition of the house is reported as "poor." An estimated regression yields Price 119.2+0.485 BDR +23.4 Bath +0.156 Hsize +0.002 Lsize (23.9) (2.61) (8.94) (0.011) (0.00048) +0.090 Age-48.8 Poor, (0.311) (10.5) R² = 0.72, SER= 41.5 (a) What is the loss in value if a homeowner lets his house run down so that its condition becomes "poor"? (b) Compute the (unadjusted) R² for the regression. (c) Is the coefficient on BDR statistically significantly different from zero?

The Census Bureau Web site gives several choices for "average income" in its historical income data. In 2006, the median income of American households was $48,201. The mean household income was $66,570. The median income of families was $58,407, and the mean family income was $77,315. The Census Bureau says, “Households consist of all people who occupy a housing unit. The term ‘family’ refers to a group of two or more people related by birth, marriage, or adoption who reside together.” Identify the reason for mean incomes for households being higher than median incomes for households.
