Below is an example of frequency data between observed and expected proportions. Can I simply run a 2-Proportion z test here? Or, would I be violating assumptions? If I were to run dozens of z tests (i.e. O-E cell comparisons), would I have to correct for multiple comparisons? Is there a better way to do this?
Technically I have 5 different sets of expected proportions -- I am just trying to determine which is most predictive of the observed data.
