Your customers are college students. You are interested in finding out which of the two new product labels is more appealing. Which inference will be required?

a) Single sample

b) Matched pairs

c) Two independent samples

d) None of the above

The correct answer to the given question is option b) Matched pairs.

In the given scenario, one needs to draw a comparison between two samples having similar characteristics in terms of their interest towards two different product labels. Hence, one should use matched pair inferential analysis where two related samples would be given two different product labels for trial.

The single sample inferential analysis is not useful as two product labels need to be tried and tested. The two independent sampling inference is useful when the two samples are not related to each other or they are entirely different.
