Question: I analyze data to develop a model of the probability that a county was cited by the state (Y) for poor DUI enforcement. I have four independent variables: Unemployment Rate (X 1 ), Percent of Adults Over 18 Who Are Married (X 2 ), a dummy variable identifying whether the County Executive is a Democrat (X 3 ), and DUI Arrests per capita (X 4 ). SPSS Output:

a-What kind of regression analysis is this (Circle One)?

Linear Regression Logistic Regression

b-Write the full regression equation (use Y, X 1 , X 2 , X 3 , and X 4 to refer to the variables as specified at the top of the page).

______________

c-What proportion of variance in State Citations is explained by this model?

______________________________________________________________

d-Using this model, what would the probability of a state citation be in a county with an Unemployment Rate of 10.00, where 38% of adults were married, where a Democrat is not County Executive, and there were 55 DUI Arrests?
