STATS

Among US adults eligible to vote, 31% identify as Democrat, 24% identify as Republican, and the rest identify otherwise. A study of 200 randomly selected US surgeons has 27% of participants identify as Democrat, and 32% as Republican, with the rest responding otherwise. Is there enough evidence to conclude that surgeons differ from the general population in their political party affiliation (more likely to identify as Republican, less likely to identify as Democrat)?
a) Specify the hypotheses and the type of test you will use. State and check all the necessary assumptions.

b) Report the results of the test. (Remember that merely presenting the output of a statistical software is not sufficient to demonstrate your knowledge; you must explicitly state which information from the output you are considering, and how you interpret that information.)
