(b) Use a calculator to verify that Ex = 154.0, Ex? = 3357.62, Ey = 241, Ey? = 9501 and Exy = 5365.4. Compute r. (Round your answer to four 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 remain constant 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 decrease as x increases.

Question
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 Ex = 154.0, Ex? = 3357.62, Ey = 241, Ey? = 9501 and Exy
= 5365.4.
Compute r. (Round your answer to four 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 remain constant 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 decrease as x increases.
