Question

John Worrall and colleagues found that the fear of losing the good opinion of one's family and peers kept people from driving home drunk (Worrall, Els, Piquero, & TenEyck, 2014), Let's say we have two independent random samples of people: those who think that their peers would disapprove of them for driving drunk and those who think that their peers either would not care or would approve of their driving drunk. We ask each person in each group to self-report the number of times that he or she has driven drunk during the past 12 months. Here are the results: Would Not Approve of Driving Drunk n! 40 x1 = 2.1 S1 = 1.8 Would Approve of Driving Drunk n2 = 25 X2 = 8.2 S2= 1.9 What is the null hypothesis? O There is no relationship between driving drunk and a person's peers approving of driving drunk O A person whose peers approve of drunk driving is more likely to drive drunk O There is a relationship between driving drunk and a person's peers approving of driving drunk.
