Pointsec (http://www.checkpoint. com/pointsec) provides security systems to protect such data. To bring home the vulnerability of mobile devices, Pointsec decided to share information about the number of such devices left behind in taxis.8 The research involved conducting a survey of taxi drivers. Staff members at Pointsec’s public relations firm called major taxi companies in nine cities in Australia, Denmark, Finland, France, Germany, Norway, Sweden, Great Britain, and the United States. Each of the cooperating companies put these interviewers in touch with about one hundred drivers. Drivers were asked how many devices of each type—cell phones, PDAs, computers, and so on—had been left in their cab over the…arrow_forwardChapter 2. Truist Bank was opened across the street from the Bank of Texas (BoT) last year. They know that they have competition from the BoT in terms of market share. After doing some basic research on the habits of their customers, they found that if a customer banked at Truist in a given month, the probability of the customer returning to Truist in the following month is 0.75 and the probability that the customer banks at BoT in the following month is 0.25. However, if a customer banks at BoT in a given month, the probability of the customer returning to BoT in the following month is 0.87 and the customer going to Truist in the following month is 0.13. Suppose that they want to consider the Markov process associated with the monthly banking habits of one customer, but they do not know where the customer banked in the previous month. Thus, they assume a 50% probability that the customer banked at Truist or BoT (that is to say, n¡(0) = 0.5 and n:(0) = 0.5). Given these initial state…arrow_forward
- 6. Consider the following game with three players: Player 1 first chooses between T and B. Then, after observing player 1's choice, Players 2 and 3 choose simultaneously between L and R. The two matrices below contain the payoffs associated with each combination of actions by the three players. Specifically, the left-hand side matrix contains the payoffs for each combination of actions by players 2 and 3 when player 1 chooses T; and the right-hand side matrix contains the payoffs for each combination of actions by players 2 and 3 when player 1 chooses B. Each cell of the matrices has a format (a, b, c), where a is the payoff of player 1; b is the payoff of player 2; and c the payoff of player 3. For example, if player 1 initially chooses T and players 2 and 3 choose L and L, then the payoff for player 1 is 3, the payoff for player 2 is 1 and the payoff for player 3 is 1. In this setting, which of the following is true? Player 2 L Player 3 L Ꭱ 3, 1, 1 2, 5, 0 R 3, 0, 5 2, 3, 3 (When…arrow_forwardThe Saunders Agency is planning to create ads for the whole season of a new reality show. They sell these ads to their customers throughout the season, as and when a customer requests for them subject to availability. Depending on off-screen scandals of the stars involved in the show, Saunders believes there are three possible scenarios. Scenario 1: A show star gets married to a rock star, another gets arrested for public indecency and two other stars have affairs. With this scenario the average demand for ads will be 40. Scenario 2: One of the three above mentioned incidents happen; the demand will be an average of 30. Scenario 3: None of the three situations mentioned in Scenario 1 happens, then the demand will be on average 20. The probability of scenario 1 happening is 0.3, scenario 2 is 0.5 and scenario 3 is 0.2. For every ad sold Saunders makes $30,000 profit. Unsold ads are sold to local cable operations at a loss of $7000 each. If a customer is turned away due to…arrow_forwardSuppose that we further alter the game from question 2 as follows: now whenever both players select the same strategy, both receive a payoff of 2. Note that this is no longer a zero-sum game. (a) Give the payoff matrix for this game. As usual, you should list Rosemary's payoffs first and Colin's payoffs second in each cell. (b) Underline the best responses for each player to each of the other players' strate- gies in your payoff matrix. Then, find and give all Pure Nash equilibria for the modified game.arrow_forward
- A researcher at a Premier University is trying to decide whether to enter a one-year teacher's college and become a high school teacher or go to graduate school, obtain an MS and Ph.D., and become a university professor. After careful consideration, he concludes that the decision should be made on the basis of the average annual income of two groups ten years after getting the bachelor's degree. In particular, he will become a university professor unless there is enough evidence to allow him to conclude that high school teacher earn more money. The researcher takes a sample of 50 university professors and 50 high school teachers, all of whom graduated with their bachelor's degrees ten years ago and determines their annual income. The results are summarized in the accompanying table: Mean and variance of annual income High school teacher X = 43.7 si= 11.8 University Professor x = 41.5 si= 46.3 At the 5 % significance level, should he become a University Professor or a High School…arrow_forwardDear tutor, please solve this question very detailed and clear, THANK YOU SO MUCH!!!arrow_forwardProblem from the bookarrow_forward
- Problem from the bookarrow_forwardA businessman is shipping a machine to another country. The cost of overhauling is $2700. If the machine fails in operation in the other country, it will cost $5500 in lost production and repairs. He estimates the probability that it will fail at 0.3 if it is not overhauled, and 0.2 if it is overhauled. Neglect the possibility that the machine might fail more than once in the 4 years (a) Prepare a payoff matrix. (b) What should the businessman do to minimize his expected costs? (a) Fill in the entries of the payoff matrix Fails Does Not Fail 8 81 (b) Would overhauling the machine before shipping minimize the businessman's expected costs?

Suppose that these three stocks are Apple stock (AAPL), Microsoft (MSFT), and Tesla (TSLA). At the end of this month, each month may move up (increase in value), move down (decrease in value) or stay the same. In this case, an experiment consists of observing the price condition across the three stocks. Each of the three conditions (move up, move down, stay same) are equally likely. How many outcomes are in the sample space? List 7 of the outcomes. (use U for move up, D for moving down and S for staying the same) Let A be the event that all the stocks have the same performance. List the outcomes in A. Let B be the event that all of stocks are different. List the outcomes in B. Let C be the event that at least two stocks move up. Are events A and C mutually exclusive? Are events B and C mutually exclusive? What is the probability of ? What is the probability of ? What is the probability of ? What is the…arrow_forward
