Finally...
I wanted to see if students around my age are mostly religiously affiliated, since I had the assumption that most students my age are independent. The result that I reached was that the alternative hypothesis was correct because the p-value was 0.028 which is less than the alpha at 0.05. We do have sufficient evidence to prove that the proportion of students in NOHS that are not affiliated with any religions are less than 50% of the population. In other words, there are more students who are religiously affilated. I have satisfied my curiosity by coming to the conclusion that more than half of the proportion of students in NOHS are religiously affilated. This number was more than I had previously believed.
