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 | 10.5 | 30.2 | 24.5 | 14.3 | 7.5 | 27.7 | 16.2 | 20.1 |
---|---|---|---|---|---|---|---|---|
y | 28 | 78 | 39 | 23 | 15 | 30 | 15 | 25 |

(b)Use a calculator to verify that (x) = 151.0, (x2) = 3317.02, (y) = 253, (y2) = 10893 and (x y) = 5623.0. Compute r. (Enter a number. Round to 3 decimal places.) As x increases, does the value of r imply that y should tend to increase or decrease? Explain your answer.Given our value of r, y should tend to decrease as x increases.Given our value of r, we can not draw any conclusions for the behavior of y as x increases. Given our value of r, y should tend to increase as x increases.Given our value of r, y should tend to remain constant as x increases.
