2. Question #1 A.r = 0.40 B.r = 0.90 C.r= 1.00 D.r = -0.10 E.r = -0.85

3. Question #2 A.r = 0.40 B.r = 0.90 C.r= 1.00 D.r = -0.10 E.r = -0.85

4. Question #3 A.r = 0.40 B.r = 0.90 C.r= 1.00 D.r = -0.10 E.r = -0.85

5. Question #4 A.r = 0.40 B.r = 0.90 C.r= 1.00 D.r = -0.10 E.r = -0.85

6. Question #5 A.r = 0.40 B.r = 0.90 C.r= 1.00 D.r = -0.10 E.r = -0.85

7. Question #6 Is the statement true or false? If false explain what is wrong with the statement. A. The correlation between eye color and weight is very strong with r = 0.95. B. If r = 1 then the scatterplot will consist of points that all lie on the same line. C. If the correlation coefficient for x and y is very small then we may say that there is no cause and effect relationship between x and y.

8. Question #7 Suppose the LSRL for hours of sleep the night before the ACT and score on the ACT is given by (Score) = 19.55 + 0.4558(Hours of sleep) If Joy had 7 hours of sleep the night before she took the ACT and her residual is 2, then her ACT score was ___________.

9. Question #8 Which of the following would you expect to have r<0? A. x = Height of student, y = weight of student B. x = Temperature of the day, y= number of people wearing coats C. x = time to swim 1 mile, y = time to swim 200 feet

10. Question #9 Given the following values for x and y. The graph of the LSRL must pass through which point. XY 24 79 1015

11. Question #10 A statistician conducts a study on x = height and y = shoe size and find that the equation of the LSRL is (Shoe size) = -5.6 + (1/5)(height) and r = 0.85. If the roles of x and y are reversed and a new equation is calculated in the form (Height) = a + b(shoe size) what are the new values of b and r?
