A survey on the use of seat belts found that 24 out of 60 males between the ages of 18 and 24 wore seat belts regularly and that 30 out of 40 females between the ages of 18 and 24 wore seat belts regularly. Does the survey provide evidence that seat belt use in this age group depends on gender? Test using a = 0.05. In answering, be sure to address each of the five steps in a test of hypothesis. If you use software to assist with calculations, indicate the function(s) that you used.
