In Exercises 1 3, use the following information: After much discussion, the Konigsberg city council decided that it would be a good thing if the city's residents succeeded in _finding a bridge walk. That is. a walk that would take the walker across each of the city's bridges once. Council members reasoned that a bridge walk would Joseter civic pride and attract tourists. They voted to close one bridge if doing so would allow the creation of a bridge walk. ( Note: The Konigsberg story presented earlier in this section is true. However, the details presented in the exercises are not.
Is there a bridge whose closure would create a bridge walk if the walk's starting point had to be different from its stopping point? If your answer is "yes," specify the bridge, draw a graph of the new six-bridge system, and describe the walk. If your answer is "no," explain why.

What hypothesis should probably be rejected? Explain. If the customer needs a connection speed of 400 kilobits to run her application programs, what is the business decision that corresponds to the decision regarding the hypotheses?arrow_forwardChapter 6, Section 4-HT, Exercise 218 - MathPad Mind-Set MattersIn 2007 a Harvard psychologist set out to test her theory that ‘‘Mind-Set Matters.”1 She recruited 75 female maids2 working in different hotels to participate in her study, and informed 41 maids (randomly chosen) that the work they do satisfies the Surgeon General’s recommendations for an active lifestyle (which is true), giving the maids examples on how their work qualifies as good exercise. The other 34 maids were told nothing. After four weeks, the exercise habits of the two groups had not changed, but the informed group had lost an average of 1.79 lbs (s=2.88) and the uninformed group had lost an average of 0.2 lbs (s=2.32). The data are stored in MindsetMatters. Based on this study, does ‘‘Mind-Set Matter”? In other words, for maids, does simply thinking they are exercising more actually cause them to lose more weight?Click here for the dataset associated with this question.1Crum, A. and Langer, E.,…arrow_forward

Among other things, the training program teaches employees to better serve the customers, be more proactive, appropriately greet customers, etc. After completion of the training program, the manager asks the group that did not receive the training program (non-training group 1) to work for a week (week 1) and then asks the group that received the training program (training group) to work the next week (week 2). During week 1 and week 2 he collects data regarding customer satisfaction from 450 and 800 people respectively using the following item: How satisfied are you with our customers?

- A recent survey points to the transformation underway in the automotive retail landscape. A study found that automobile executives believe the number of physical automotive retail outlets, as we know them today, will be reduced by 30% to 50%. Eighty-two percent of automobile executives strongly agree that the only viable option for physical retail outlets will be the transformation into service factories, used car hubs, or focusing on an ID-management approach, where the customer is recognized at every single touchpoint. What additional information would you want to know about the survey before you accepted the results of the study?arrow_forwardAs part of a quality improvement initiative, Consolidated Electronics employees complete a three-day training program on teaming and a two-day training program on problem-solving. The manager of quality improvement has requested that at least 8 training programs on teaming and at least 10 training programs on problem-solving should be offered during the next six months. In addition, senior-level management has specified that at least 25 training programs must be offered during this period. Consolidated Electronics uses a consultant to teach the training programs. During the next quarter, the consultant has 84 days of training time available. Each training program on teaming costs P10,000 and each training program on problem-solving costs P8,000. Formulate a linear programming model that can be used to determine the number of training programs on teaming and the number of training programs on problem-solving that should be offered in order to minimize total cost.
