Textbook Question

Chapter 9.1, Problem 1E

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.

In order to find a new way to increase route setting efficiency, the route setters at a gym begin using two styles of setting to determine which would be better at creating separation at competitions. The two styles of setting used were modern and classic. Over the course of several months, 56 boulders were set using the modern style and 49 boulders were set using the classic style. The number of routes that were completed at least once was recorded. For the modern style boulders, 37 of them were completed. For classic style, 30 were completed. Research Question: Are classic boulders harder to complete than modern boulders? State the observed statistic using relative risk What is the interpretation of the relative risk calculated in problem 52?
