Based on your calculations, which of the following represents your decision regarding the null hypothesis?
As alcohol-related problems are a concern on college campuses, research has been conducted regarding students’ perceptions of drinking behavior. For example, one study found students have misconceptions regarding what is considered excessive (“binge”) drinking (White et al, 2004). Imagine you believe students’ definition of binge drinking will differ from the government’s definition. More specifically, you hypothesize students will overestimate the number of drinks needed to be consumed to be defined as binge drinking. To test this hypothesis, a group of college students are asked, “How many drinks in a row must a man drink in order to define it as “binge drinking?” The responses of some of the students in this class are summarized as:
N = 16
= 7.94
s = 4.63
a. Do not reject H0 (p > .05)
b. Reject H0 (p < .05)
c. Reject H0 (p < .01)
d. Reject H0 (p > .01)
b. Reject H0 (p < .05)
