This has been stumping me for a bit now and I'm struggling to find the answer by googling. I am trying to compare two percentages to determine if they are statisticall different. The issue is that one of the groups is a subgroup of the second group.
I'm going to change the information around a little bit to keep confidential things confidential, but here's an equivalent setup:
Let's say that I have 100 student athletes out of a population of 1000 students. 70% of the athletes like to eat at Chipotle. 55% of the entire student body likes to eat at Chipotle. I have no information specific to "non-student athletes" (unless it could be computed mathematically?)
How to I determine if the percent of student athletes who like Chipotle is statistically different from the percent of the entire student body that likes Chiptole?
Chi squared tests seem to be the answer for those situations in which you have two exclusive groups (e.g. men vs. women). But can I use the same test for the group-subgroup analysis? And if so, how do I do it?
Thank you kindly!
