We did a movie project where we watched a film from the 70s and a film from the 2000s and counted the violent scenes in each movie. We have to do a 2 sample comparison.
The null hypothesis is that there is equal violence in both films
Alternate hypothesis is that the newer film is more violent
According to the instructions, "The 1970s movies is your "population". You are counting the number of incidents of violence. These are your "n". The newer movie is a sample."
These instructions make no sense to me. I can't do a mean test, as there is nothing to average together. That only leaves a proportion test, but for that I need a phat value, which is x/n. I have no idea what x could be...
