Devore (7th Ed.) Page 135, Exercise 6. 2. Devore (7th Ed.) Page 143, Exercise 12. 3. Suppose X is a normal rv with mean 60 and standard deviation 15. Use Table A3 on pages 668–9 of Devore 7e to compute the following: (a). Pr[ X 70] (b). Pr[ X 55] (c). Pr[55 X 70] (d) the 80th percentile of the distribution of X. 4. Devore (7th Ed.) Page 155, Exercise 42. 5. Devore (7th Ed.) Page 162, Exercise 63. 6. Devore (7th Ed.) Page 163, Exercise 69. 7. Probability plots You can use MINITAB or other software in this question. Consider the following sample of n = 10 observations: 71 . 5 , 62 . 3 , 68 . 1 , 61 . 4 , 61 . 5 , 64 . 1 , 64 . 7 , 61 . 1 . 59 . 9 , 63 . 1 (a) Make a table of 10 rows in which the first column (C1) consists of these 10 observations. In the next column C2, place these same observations sorted into ascending order (the “order statistics” x ( i ) ).

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
