A random sample of n = 8 universities in California gave the following information about enrollments an X 11.3 29.6 24.5 14.3 7.5 27.7 16.2 20.1 27 77 39 23 15 30 15 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.) Choo This answer has not been graded yet. (b) Use a calculator to verify that E(x) = 151.2, E(x?) = 3298.58, E(y) = 251, E(y ) = 10683 and S(x y) = 5557.7. Computer. (Enter a number. Round to 3 decimal places.) As x increases, does the value of r imply that y should tend to increase or decrease? Explain your answer. O Given our value of r, y should tend to decrease as x increases. O Given our value of r, y should tend to increase as x increases. O 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. Need Help? Read It
