5. For this problem, we have used the same X and Y values that appeared in Problem 4, but we have changed the X, Y pairings:

X Y 1 6 2 8 4 2 5

a. Sketch a graph showing these reorganized data.

b. Estimate the Pearson correlation just by looking at your graph.

c. Compute the Pearson correlation. (Note: Much of the calculation for this problem was done already in Problem 4.)

If you compare the results of Problem 4 and Problem
