What happens when you break social norms? Pedestrians walking on sidewalks typically follow the same traffic patterns as cars driving in the streets. What happens if you walk on the wrong side of the sidewalk? Do sex, location, and speed of walker affect the number of people in the oncoming traffic that run into you? Data were collected using both a male experimenter and a female experimenter and are given in the data file SocialNormsSex.

a. Is there an association between whether you collide with oncoming pedestrians and the sex of the experimenter? Calculate appropriate descriptive statistics about what these numerical and graphical summaries reveal to you. Explain how you are deciding.

b. Carry out a simulation-based test of significance to test whether there is evidence of an association between whether you collide with oncoming pedestrians and the sex of the experimenter. State the hypotheses and an appropriate conclusion and be sure to include your reasoning for your conclusion.
