As a class project, a group of students performed an observation study. The students waited at a busy intersection and recorded the gender of each driver they saw and whether or not that driver was currently using a cell phone while they were driving. Some of the students thought that males were more likely to use cell phones than females while others in the group thought that the opposite was true. Use the data they collected below to test the null hypothesis that there is no association between gender and cell phone use while driving. Which 2 should be used to test this null hypothesis
