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 n1 = 40 x1 = 2.1 Sj = 1.8 Would Approve o Driving Drunk D2-25 x2 = 8.2 S2= 1.9 What is the most accurate alternative hypothesis? O There is a relationship between driving drunk and a person's peers approving of driving drunk O There is no relationship between driving drunk and,a person's peers approving of driving drunk. A person whose peers approve of drunk driving is more likely to drive drunk. O A person whose peers approve of drunk driving is less likely to drive drunk

Explanation / Answer

Here the question entails that is the fear of losing respect or good opinion among peers and family will keep drin and drive behavior at bay. SO here null hypothesis will mean that approval of family and peer doesnt affect the drink and drive behaviors.

Som Here the most accurate alternative Hypothesis will be that A person whose peers approve of drunk driving is more likely to drive drunk. Here option C is correct.

Here Option A could be correct but it only talks about "Association" between variables driving drunk and "Peers approving of driving drunk". But we want a direction of relationship which is provided by Option C.
