- The manager of a theater that is open to residents of two towns, A and B, wants to know if the proportion of households from A that use the library is smaller than the proportion of households from B. In order to test this, the manager asks 45 households in A and 49 households in B whether anyone in their household had used the theater last summer. 23 of the households surveyed in A responded "yes", and 35 of the households in B responded "yes". Find the p-value that would be used to make a conclusion for this hypothesis test.The National Highway Association is studying the relationship between thenumberof bidders on a highway project and the winning (lowest) bid for the project.

- Sarah chose to live on the honors floor of her dorm because she was told that the students on that floor would be quiet and studious. She was told that students on the honors floor study 10.5 hours per week. After living on the honors floor for a few months, Sarah is convinced that the students around her study less than 10.5 hours a week. To test her claim, Sarah polls 10 students on her floor regarding the number of hours per week that they spend studying. Use the results in the table below to test Sarah’s claim at the 0.05 level of significance.
