Chapter 3: Q64E (page 194)

Do social robots walk or roll?Refer to the International Conference on Social Robotics (Vol. 6414, 2010) study of the trend in the design of social robots, Exercises 3.10 (p. 168) and 3.37 (p. 181). Recall that in a random sample of 106 social robots, 63 were built with legs only, 20 with wheels only, 8 with both legs and wheels, and 15 with neither legs nor wheels. If a social robot is designed with wheels, what is the probability that the robot also has legs?

Step by step solution

01

 Step 1: Random Sample

Random samplingis a sampling strategy in which every test has an equal chance of being selected. A random sample is intended to provide an impartial reflection of the overall population.

02

Finding the probability that the robot has wheels and legs

A = Robots with both legs and wheels (8)

B = Total number of robots (106)

P=RobotswithlegsandwheelsTotalRobots=8106=0.075=7.5%

Therefore, the probability that a robot designed with wheels also has legs is 7.5%.

Characteristics of a new product. The long-run success of a business depends on its ability to market products with superior characteristics that maximize consumer satisfaction and that give the firm a competitive advantage (Kotler & Keller, Marketing Management, 2015). Ten new products have been developed by a food-products firm. Market research has indicated that the 10 products have the characteristics described by the following Venn diagram:

  1. Write the event that a product possesses all the desired characteristics as an intersection of the events defined in the Venn diagram. Which products are contained in this intersection?
  2. If one of the 10 products were selected at random to be marketed, what is the probability that it would possess all the desired characteristics?
  3. Write the event that the randomly selected product would give the firm a competitive advantage or would satisfy consumers as a union of the events defined in the Venn diagram. Find the probability of this union.
  4. Write the event that the randomly selected product would possess superior product characteristics and satisfy consumers. Find the probability of this intersection.
  5. Two of the 10 products will be selected for an ad campaign. How many different pairs of products are possible?

For two independent events, A and B, P (A) = .4 and P(B) = .2 :

a. Find P (A鈭〣)

b. Find P (A/B)

c. Find P (A鈭�B)

Chance of an Avon sale.The probability that an Avon salesperson sells beauty products to a prospective customer on the first visit to the customer is .4. If the salesperson fails to make the sale on the first visit, the probability that the sale will be made on the second visit is .65. The salesperson never visits a prospective customer more than twice. What is the probability that the salesperson will make a sale to a particular customer?

Testing a watch manufacturer鈥檚 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鈥檚 watches with the intention of testing the claim.

  1. Assuming that the manufacturer鈥檚 claim is correct, what is the probability that none of the watches are as accurate as claimed?
  2. Assuming that the manufacturer鈥檚 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鈥檚 claim? Explain.
  4. Suppose that none of the watches tested are as accurate as claimed. Is it necessarily true that the manufacturer鈥檚 claim is false? Explain.

Exit poll candidates and voters.In an exit poll, 45% of voters said that the main issue affecting their choice of candidates was the economy, 35% said national security, and the remaining 20% were not sure. Suppose we select one of the voters who participated in the exit poll at random and ask for the main issue affecting his or her choice of candidates.

  1. List the sample points for this experiment.
  2. Assign reasonable probabilities to the sample points.
  3. What is the probability that the main issue affecting randomly selected voters鈥� choice was either the economy or national security?
