Exam 14: Building Multiple Regression Models

Abby Kratz,a market specialist at the market research firm of Saez,Sikes,and Spitz,is analyzing household budget data collected by her firm.Abby's dependent variable is weekly household expenditures on groceries (in $'s),and her independent variables are annual household income (in $1,000's)and household neighborhood (0 = suburban,1 = rural).Regression analysis of the data yielded the following table. For a suburban household with ______ annual income,Abby's model predicts weekly grocery expenditure of $235.
