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.

(b) Use a calculator to verify that 2(X) = 153.0, 2(X2) = 3400.42, 2(y) = 247, 2(y2) = 10377 and 2(x y) = 5620.6. 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. Q Given our value of r, y should tend to increase as x increases. 0 Given our value of r, we can not draw any conclusions for the behavior of y as x increases. 0 Given our value of r, y should tend to remain constant as x increases. 0 Given our value of r, y should tend to decrease as X increases
