Chapter 3: Q104SE (page 204)

Workers鈥� unscheduled absence survey. Each year CCH, Inc., a firm that provides human resources and employment law information, conducts a survey on absenteeism in the workplace. The latest CCH Unscheduled Absence Surveyfound that of all unscheduled work absences, 34% are due to 鈥減ersonal illness,鈥� 22% for 鈥渇amily issues,鈥� 18% for 鈥減ersonal needs,鈥� 13% for 鈥渆ntitlement mentality,鈥� and 13% due to 鈥渟tress.鈥� Consider a randomly selected employee who has an unscheduled work absence.

a. List the sample points for this experiment.

b. Assign reasonable probabilities to the sample points.

c. What is the probability that the absence is due to something other than 鈥減ersonal illness鈥�?

Short Answer

Expert verified
  1. The sample points are PI, F, P and E.
  2. The probability are 0.390, 0.252, 0.206 and 0.149.
  3. The probability is 0.609

Step by step solution

01

Important formula

The formula for probability is P=favourableoutcomestotaloutcomes.

02

The sample points.

a)

The sample points are

Here PI=personal illness

F=family issue

P=personal needs

E=entitlement mentality.

Thus, the sample points are PI, F, P, E.

03

Step 3:The possible probabilities.

b)

P(PI)=0.340.87=0.391

P(F)=0.220.87=0.253

P(P)=0.180.87=0.207

P(E)=0.130.87=0.149

Hence, the probability is 0.391, 0.253, 0.207, and 0.149.

04

The probability that the absence is due to something other than “personal illness”.

c)

P(FandPandE)=0.22+0.18+0.130.87=0.609

Therefore, the probability is 0.609

Speeding linked to fatal car crashes. According to the National Highway Traffic and Safety Administration鈥檚 National Center for Statistics and Analysis (NCSA), 鈥淪peeding is one of the most prevalent factors contributing to fatal traffic crashes鈥� (NHTSA Technical Report, August 2005). The probability that speeding is a cause of a fatal crash is .3. Furthermore, the probability that speeding and missing a curve are causes of a fatal crash is .12. Given speeding is a cause of a fatal crash, what is the probability that the crash occurred on a curve?

Suppose the events B1and B2are mutually exclusive and complementary events, such thatP(B1)=.75andP(B2)=.25 Consider another event A such that role="math" localid="1658212959871" P(AB1)=.3, role="math" localid="1658213029408" P(AB2)=.5.

  1. FindP(B1鈭�A).
  2. FindP(B2鈭�A)
  3. Find P(A) using part a and b.
  4. Findrole="math" localid="1658213127512" P(B1A).

Using game simulation to teach a course. In Engineering Management Research (May 2012), a simulation game approach was proposed to teach concepts in a course on production. The proposed game simulation was for cola or television production. The products are two color television models, A and B. Each model comes in two colors, red and black. Also, the quantity ordered for each model can be 1, 2, or 3 televisions. The choice of model, color, and quantity is specified on a purchase order card.

a. Using a tree diagram, list how many different purchase order cards are possible. (These are the sample points for the experiment.)

b. Suppose, from past history, that black color TVs are in higher demand than red TVs. For planning purposes, should the engineer managing the production process assign equal probabilities to the simple events, part a? Why or why not?

Working on summer vacation. Is summer vacation a break from work? Not according to a Harris Interactive (July 2013) poll of U.S. adults. The poll found that 61% of the respondents work during their summer vacation, 22% do not work while on vacation, and 17% are unemployed. Assuming these percentages apply to the population of U.S. adults, consider the work status during the summer vacation of a randomly selected adult.

a. What is the Probability that the adult works while on summer vacation?

b. What is the Probability that the adult will not work while on summer vacation, either by choice or due to unemployment?

Management system failures. Refer to the Process Safety Progress (December 2004) study of 83 industrial accidents caused by management system failures, Exercise 2.150(p. 142). A summary of the root causes of these 83 incidents is reproduced in the following table. One of the 83 incidents is randomly selected and the root cause is determined.

a. List the sample points for this problem and assign reasonable probabilities to them.

b. Find and interpret the probability that an industrial accident is caused by faulty engineering and design.

c. Find and interpret the probability that an industrial accident is caused by something other than faulty procedures and practices.
