I understand the whole concept of SE and CI, but I am confused on how to apply these concepts to FRQs and how to answer questions with them. The 2017 FRQ you gave as an example did not ask for anything related to SE or CI (or maybe im missing something). Can you please clarify on how to apply this to the FRQ?
The question did the work for you in that it analyzed a set of data, found the standard deviation, and then found the standard error of the mean. There is a set of questions that go along with that FRQ but she was going over how to interpret data like that. You can find the other questions and their answers here: https://secure-media.collegeboard.org/ap/pdf/ap17-sg-biology.pdf
OHH ok that makes a lot more sense now. Thank you!
