10. Please tell me 4 parameters that are directly forecasted by the model?

In 2012, a scientist found that 30% of the adult population believe that the sun goes around Earth. A recent survey revealed that 203 of 1974 adults surveyed believe that the sun goes around Earth. Is this a significant change from 2012? Set up the hypotheses (null and alternative) to test whether the proportion of the adult population who believe that the sun goes around Earth has changed. You can state them in words if you want, but they must contain the parameter of interest.

Can somebody give me the rules on how to classify the equilibrium points?
