At a stop sign, some drivers come to a full stop, some come to a 'rolling stop' (not a full stop, but slow down), and some do not stop at all. We would like to test if there is an association between gender and type of stop (full, rolling, or no stop). We collect data by standing a few feet from a stop sign and taking note of type of stop and the gender of the driver. Below is a contingency table summarizing the data we collected. Male 6 16 4 06.24 5.76 3.64 03.36 Female 6 15 3 Full stop Rolling stop No stop If gender is not associated with type of stop, how many males would we expect to not stop at all?

down), and some do not stop at all. We would like to test if there is an association between gender and
type of stop (full, rolling, or no stop). We collect data by standing a few feet from a stop sign and taking
note of type of stop and the gender of the driver. Below is a contingency table summarizing the data we
collected.
