(b) Use a calculator to verify that Ex = 150.4, Ex² = 3251.86, Ey = 250, Ey² = 10630 and Exy = 5484.8. 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 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 remain constant as x increases. Given our value of r, y should tend to increase as x increases.

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.
