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?

Short Answer

Expert verified
  1. 12 sample points. The sample points are AR1, AR2, AR3, ABL1, ABL2, ABL3, BR1, BR2, BR3, BBL1, BBL2, and BBL3.
  2. NO, the probability to the sample point that was determined in part a should not be equal.

Step by step solution

01

Important formula

The formula for probability isP=favourableoutcomestotaloutcomes

02

Draw a tree diagram.

Here given: The products are two colors television models, A and B. Each model comes in two colors, red(R) and black(BA).Thequantity ordered for each model can be 1, 2, or 3 televisions.

The tree diagram is

Hence, the sample points are

AR1, AR2, AR3, ABL1, ABL2, ABL3, BR1, BR2, BR3, BBL1, BBL2, BBL3.

03

what is the result if the probability to the sample point that was determined in part a should be equal.

NO, the probability to the sample point that was determined in part a should not be equal because if the engineer assigns similar probabilities to black and red TVs then there will be a shortage of black TVs. Since the demand for them was higher, and a surplus of red TVs.

Therefore, NO, the probability to the sample point that was determined in part a should not be equal.

Appeals of federal civil trials. The Journal of the American Law and Economics Association (Vol. 3, 2001) publishedthe results of a study of appeals of federal civil trials. Thefollowing table, extracted from the article, gives a breakdownof 2,143 civil cases that were appealed by either theplaintiff or the defendant. The outcome of the appeal, aswell as the type of trial (judge or jury), was determined foreach civil case. Suppose one of the 2,143 cases is selected

at random and both the outcome of the appeal and type of trial are observed.

Firefighter glove sizing. Human Factors (December 2015) published a study on how well firefighter gloves fit. In a group of 586 firefighters who reported their glove size, the researchers determined whether the gloves fit well or poorly by gender. The data are summarized in the accompanying table. Consider the gender and glove fit status of a randomly selected firefighter.

a. List the sample points for this experiment.

b. Assign reasonable probabilities to these sample points.

c. Find the probability the firefighter is a female.

d. Find the probability the glove fits well.

e. Find the probability the firefighter is a female and has a well-fitting glove.

f. Find the probability the firefighter is a female or has a well-fitting glove.

Social networking Web sites in the United Kingdom. In the United States, MySpace and Facebook are considered the two most popular social networking Websites. In the United Kingdom (UK), the competition for social networking is between MySpace and Bebo. According to Nielsen/ Net Ratings (April 2006), 4% of UK citizens visit MySpace, 3% visit Bebo, and 1% visit MySpace and Bebo.

a. Draw a Venn diagram to illustrate social networking sites in the United Kingdom.

b. Find the probability that a UK citizen visits either the MySpace or Bebo social networking site.

c. Use your answer to part b to find the probability that a UK citizen does not visit either social networking site.

Testing a watch manufacturer’s claim. A manufacturer of a new Smart Watch claims that the probability of its watch running more than 1 minute slow or 1 minute fast after 1 year of use is .05. A consumer protection agency has purchased four of the manufacturer’s watches with the intention of testing the claim.

  1. Assuming that the manufacturer’s claim is correct, what is the probability that none of the watches are as accurate as claimed?
  2. Assuming that the manufacturer’s claim is correct, what is the probability that exactly two of the four watches are as accurate as claimed?
  3. Suppose that only one of the four tested watches is as accurate as claimed. What inference can be made about the manufacturer’s claim? Explain.
  4. Suppose that none of the watches tested are as accurate as claimed. Is it necessarily true that the manufacturer’s claim is false? Explain.
