Question: I analyze data to develop a model of the number of DUI Arrests Per Capita (Y) by county in a year. I have three independent variables: Unemployment Rate (X ₁ ), Percent of Adults Over 18 Who Are Married (X ₂ ), and a dummy variable identifying whether the County Executive is a Democrat (X ₃ ). SPSS Output:
