A random sample of 10 statistics students produced the following data, where x is the second exam score out of 80, and y is the final exam score out of 200.

x (Second exam score)	y (Final exam score)
65	175
67	133
71	185
70	163
66	126
75	198
67	153
70	163
71	159
69	151

a) Find the correlation coefficient. Can you predict the final exam score of a randomly selected student if you know the third exam score?

b) What would you predict the final exam score to be for a student who scored a 66 on the third exam?

c) What would you predict the final exam score to be for a student who scored a 90 on the third exam?
