The null hypothesis being tested is that there is no significant difference between search engine 1 (11ea7a43_e9ed_9369_89bd_e107bd05e8ec_TB3933_00) and search engine 2 (11ea7a43_e9ed_936a_89bd_113f795e179c_TB3933_00) in their ability to locate specific information using specified keywords. This is indicated by the "≠" symbol in choice B, which represents a two-tailed hypothesis test. The other choices either have different symbols or involve different variables, and are therefore not appropriate for this scenario.
