Conclusion
Two hundred people were asked to choose either Team Dean or Team Sam, who are both characters in the show Supernatural. First, I asked if they watch the show Supernatural to ensure that the results are valid. Then, I asked the question, "Are you team Dean or team Sam?"
Sampling Method
I used the convenience sampling method by asking easy to reach people on social media.
Based on my research, there is not sufficient evidence at 5% level of significance to support the claim that more than 80% of surveyed people will vote for Dean.
I chose the convenience sampling method because it was hard to find people at school who watch the show. By using social media, I could pinpoint people who watch Supernatural and ask them my question.
My hypothesis was that more than 80% of the surveyed people would choose team Dean.
