Answers to odd numbered problems are in the back of the text, answers to listed even numbered problems are here

1.1 - 17, 21, 33, 35, 41

2.1 - 11, 13, 17

2.2 - 4, 5, 7, 11, 15, 19, 23, 31 (also do stem-and-leaf), 39 (on what assumptions is your answer to c based)

2.3 - 1, 8 (also, should that be in one, two, or three dimensions), 9

3.1 - 3, 11, 15, 17, 21, 23, 31, 37, 49, 52 (also calculate the midrange wherever you calculated the mean and median)

3.2 - 17, 21, 23, 33cdef (s=.04, x-bar = .87), 46

3.3 - 9, 13 (exact s=10.9), 15, 17

3.4 - 9, 13, 15 (mu=3.99, sigma=1.78), 19

3.5 - 3, 5, 11

**First Test**

5.1 - 12, 13, 17 (what are you assuming?), 19, 25, 33, 35, 39, 53

5.2 - 5, 7 (must assume simple events are equally likely for 7 and 11), 9, 11, 13, 17, 19, 25, 41

5.3 - 7, 9, 13, 23

5.4 - 3, 7, 9, 11, 15 (there is inadequate information to solve this problem), 19, 27, 33, 39

5.5 - 5, 9, 15, 17, 21, 23, 27, 29, 31, 41, 47, 50, 53

7.2 - 5, 7, 11, 13, 17, 21, 31, 37, 39, 50

7.3 - 3, 5, 11, 21, 31

7.5 - 5, 7, 15, 24, 27

8.1 - 11, 15, 21

8.2 - 7, 11

**Second Test**

9.1 - 15, 17, 19, 29, 39

9.2 - 13

9.3 - 5, 9, 13, 15, 21

10.1 - 9, 11, 15, 21, 23, 29, 31, 35, 37

10.2 - 11, 13, 15, 21, 23b, 27b, 31, 35

10.3 - 17, 19 (we have not covered the t-distribution, but I want you to think about using confidence intervals to test hypotheses)

10.4 - 3, 7, 11, 13, 17

12.1 - 5, 7, 11 (ratios are available at http://us.mms.com/us/about/products/), 17

12.2 - 5, 13, 19

**Third Test**

4.1 - 15, 17, 21, 26 (I selected this problem becuuse of d, consider also subtracting a millimeter from all measurements (or just the tibia measurements)), 42, 43 (I could argue for other answers)

4.2 - 10 (you should calculate x-bar, y-bar, s_x, s_y, and r), 15, 20 (also convert to inches)

4.3 - 3, 12
