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 11.1 30.0 24.5 14.3 7.5 27.7 16.2 20.1 y 22 69 39 23 15 30 15 25 Use a calculator to verify that Σx = 151.4, Σx2 = 3317.94, Σy = 238, Σy2 = 9270 and Σxy = 5287.6. Compute r. (Round your answer to four decimal places.)

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 | 11.1 | 30.0 | 24.5 | 14.3 | 7.5 | 27.7 | 16.2 | 20.1 |
|---|---|---|---|---|---|---|---|---|
| y | 22 | 69 | 39 | 23 | 15 | 30 | 15 | 25 |
Use a calculator to verify that Σx = 151.4, Σx2 = 3317.94, Σy = 238, Σy2 = 9270 and Σxy = 5287.6.
Compute r. (Round your answer to four decimal places.)
