I wonder if a set of data is missing.
This the data missing:
Do larger universities tend to have more property crime? University crime statistics are affected by a variety of factors. The surrounding community, accessibility given to outside visitors, and many other factors influence crime rate. Let x be a variable that represents student enrollment (in thousands) on a university campus, and let y be a variable that represents the number of burglaries in a year on the university campus. A random sample of n = 8 universities in California gave the following information about enrollments and annual burglary incidents.
x 12.1 30.4 24.5 14.3 7.5 27.7 16.2 20.1
y 24 68 39 23 15 30 15 25
