Proximity of fast-food restaurants to schools and adolescent overweight. A California study looked at the relationship between the presence of fast-food restaurants near schools (within a 0.5 mile radius) and being overweight among middle and high school students.10 Whether a student was overweight was determined based on each student's responses to the California Healthy Kids Survey (CHKS). A database of latitude-longitude coordinates for schools and restaurants was used to determine proximity. Here are the data:

Use logistic regression to study the question of whether or not being overweight is related to the proximity of fast-food restaurants to schools. Write a short paragraph summarizing your conclusions.
