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 13.3 28.6 24.5 14.3 7.5 27.7 16.2 20.1 y 25 75 39 23 15 30 15 25 Use a calculator to verify that Σx = 152.2, Σx2 = 3289.58, Σy = 247, Σy2 = 10275 and Σxy = 5450.9. Compute r. (Round your answer to four decimal places.)
