Question: Refer to Exercise. Some students were asked if they preferred C or P, while other students were asked if they preferred P or C. Of the 159 respondents, 86 responded with the first drink presented. Test the hypothesis that the first drink presented is more likely to be selected than the second drink presented.
Exercise: In a survey of students at the University of California, Davis (UCD), students were asked which of two popular soft drinks they preferred-let's call them brand C and brand P. Of the 159 respondents, 80 preferred brand P and 79 preferred brand C. Assuming that these students represent all students at UCD, test whether there is a preference for one drink over the other for students at UCD.
