Final answer:
The question about the number of times college students reported hooking up cannot be answered without specific study results. Sexual behavior research can be influenced by societal double standards and varies across different contexts.
Step-by-step explanation:
Without specific data from the study referenced in the question about college students' sexual practices, it is not possible to determine how many times the majority of students reported hooking up. The trends in sexual behaviors can vary widely depending on the cultural, social, and even temporal context. For example, historical data might suggest different patterns than contemporary studies. Sexual behavior studies often involve sensitive data collection methods such as surveys or interviews, and findings can reflect double standards in society, such as those identified by researcher Ira Reiss. These double standards historically subjected women and men to different sexual expectations, which could influence self-reported sexual activity amongst college students.
