A researcher is investigating differences in homicide rates across northern and southern cities. She collects data and finds that the mean homicide rate in four large southern cities is 95.45.The mean homicide rate for four large northern cities was 81.09. What would this researcher’s null and alternative hypotheses look like? Write your answers out in words (worth up to 5 points).

Now, use the null and alternative hypotheses that you constructed in the last question and rewrite them using symbols instead of words (worth up to 5 points).

There has long been an analogy between hypothesis testing and court proceedings. Explain how the presumption of innocence during a trial could possibly be related to hypothesis testing in statistics (worth up to 10 points).
