Chapter 1:
1-8: Describe the use of sensitivity analysis and postoptimality analysis in analyzing the results.
1-10: Why do you think many quantitative analysts don\u2019t like to praticipate in the implementation process? What could be done to change this attitude?
1-14: Gina Fox has started her own company. Foxy Shirts, which manufactures imprinted shirts for special occasions.

One hundred fifty-five people who did no exercising had colds, while the remainder of the people with colds were involved in a weekly exercise program. Half of the 1,000 employees were involved in some type of exercise.<\/p>\n

David Mashley teaches two undergraduate statistics courses at Kansas College. The class for Statistics 201 consists of 7 sophomores and 3 juniors. The more advanced course, Statistics 301, has 2 sophomores and 8 juniors enrolled. As an example of a business sampling techinique, Professor Mashley randomly selects, from the stack of Statistics 201 registration cards, the class card of one student and then places that card back in the stack. If that student was a sophomore, Mashley draws another card from the Statistics 201 stack; if not, he randomly draws a card from the Statistics 301 group. Are these two draws independent events? What is the probabilty of<\/p>\n
(a) a junior\u2019s name on the first draw<\/p>\n
(b) a junior\u2019s name on the second draw, given that a sophomore\u2019s name was drawn first?<\/p>\n
(c) a juniors\u2019s name on the second draw, give that a junior\u2019s name was drawn first?<\/p>\n
(d) a sophomore\u2019s name on both draw\u2019s?<\/p>\n
(e) a junior\u2019s name on both draw\u2019s?<\/p>\n
(f) one sophomore\u2019s name and one junior\u2019s name on the two draws, regardless of order drawn?<\/p>\n
2-24: The Boston South Fifth Street Softball League consists of three teams: Mama\u2019s Boys, team 1; the Killers, team 2; and the Machos, team 3. Each team plays the other teams just once during the season. The win-loss record for the past five years is as follows:

Mama\u2019s Boys (1) X 3 4
The Killers (2) 2 X 1
The Machos (3) 1 4 X<\/p>\n
Each row represents the number of wins over the past five years. Mama\u2019s Boys beat the Killers 3 times, beat the Machos 4 times, and so on.<\/p>\n
The schedule for the Killers next year is as follows:
Game 1: The Machos
Game 2: The Mama\u2019s Boys
(a) What is the probability that the Killers will win their first game? =
(b) What is the probability that the Killers will win their last game? =
(c) What is the probability that the Killers will break even-win exactly one game?
(d) What is the probability that the Killers will win every game? = .8
(e) What is the probability that the Killers will lose every game?
(f) Would you want to be the coach of the Killers?<\/p>\n

2-32. There are 10 questions on a true\u2013false test. A student feels unprepared for this test and randomly guesses the answer for each of these.<\/p>\n
(a)What is the probability that the student gets exactly 7 correct?<\/p>\n
(b)What is the probability that the student gets exactly 8 correct?<\/p>\n
(c)What is the probability that the student gets exactly 9 correct?<\/p>\n
(d)What is the probability that the student gets exactly 10 correct?<\/p>\n
(e)What is the probability that the student gets more than 6 correct?<\/p>\n","protected":false},"excerpt":{"rendered":"
