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 10.9 29.6 24.5 14.3 7.5 27.7 16.2 20.1 26 39 M 30 25 (a) Make a scatter diagram of the data. Then visualize the line you think best fits the data. (Submit a file with a maximum size of 1 MB.) Browse.. No file selected. This answer has not been graded yet. (b) Use a calculator to verify that E(x) = 150.8, E(x2) = 3289.70, E(y) = 248, Z(y2) = 10326 and E(x y) = 5476.8. Compute r. (Enter a number. Round to 3 decimal places. ) As x increases, does the value offr imply that y should tend to increase or decrease? Explain your answer. Given our value of r, y should tend to increase 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 decrease as x increases. Given our value of r, y should tend to remain constant as x increases
