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	28.8	24.5	14.3	7.5	27.7	16.2	20.1
y	28	77	39	23	15	30	15	25

(b)Use a calculator to verify that (x) = 149.6, (x²) = 3234.42, (y) = 252, (y²) = 10738 and (x y) = 5485.0. Compute r. (Enter a number. Round to 3 decimal places.)

(I am not understanding how to Compute R. )
