Does the order in which wine is presented make a difference? Subjects were asked to taste two different win samples in sequence, and to then indicate which wine they prefered. Both samples given to the subejcts were the same wine, although the subjects were expecting to taste two different samples of a particular variety. Of the 32 subjects in the study, 22 selected the wine presented first when presented with the two identical wine samples.
a) Does the data give good reason to conclude that the subjects are not equally likely to choose either of the two wines when presented with two identical wine samples in sequence?
b) The subjects were recruited in Ontario, Canada, via advertisments to participate in a study of "attitudes and values towards wine." Can we generalize our conclusions to all wine drinkers? Explain.
