Question: x- represents student enrollment (in thousand) on a university campus.
y-represents the number of burglaries in a year on a university campus.
n=8

X- 12.5 30.0 24.5 14.3 7.5 27.7 16. 20.1
Y- 26 73 39 23 15 30 15 25

a- Make a scatter diagram and graw the line you think best fits the data
b-would you say the correlation is low, moderate, or high? positive or negative?
c- using a calculator, verify that x= 152.8, x2= 3350.98, y= 246, y2=10,030 and xy= 5488.4. compute r . As x increases, does the value of r imply that y should tend to increase or decrease. Explain.
