One of the main concerns regarding the HPV vaccine is that once vaccinated teen-agers and young adults will engage in risky sexual behaviors because they have immunity to HPV, which is known to cause cervical, tongue, and mouth cancers, among others. Researchers wonder if this concern about the vaccine is valid. They seek to answer the question: Are college-aged students (all genders) who received the HPV vaccine (all 3 doses) more likely to engage risky sexual practices (defined as having either sex without a condom or more than two sexual partners) than college-aged students who did not receive the HPV vaccine? Students enrolled at 50 colleges across the United States received an email with a link to an anonymous questionnaire, which asked questions about whether they received the HPV vaccine and their sexual practices.
Biostatistics question:
State a null & alternative hypothesis. Additionally please explain if you’d use a one- or two-sided hypothesis test. Explain your answer.
