The following data was collected by a Civil Engineering Ph.D. student. The response variable is the number of deer-vehicle crashes given a half-mile section of highway located in Ashtabula County. The half-mile sections were supposedly scattered about the community. Find an appropriate model which will be useful in predicting the number of deer-vehicle crashes using the candidate regressor variables. Interpret your results.

X1 = number of vertical curves in the half-mile section

X2 = number of horizontal curves in the half-mile section

X3 = number of ditches in the half-mile section

X4 = number of residences in the half-mile section

X5 = number of driveways in the half-mile section

X6 = percent of half-mile section that was adjacent to forest land

There are 20 observations total.
