Question: Two advertisements for tourism and vacation on Turks and Caicos Islands, which ran in business publications in May 2007, were compared for their appeal. A random sample of eight people was selected, and their responses to ad 1 were recorded. Another random sample, of nine people, was shown ad 2, and their responses were also recorded. The response data are as follows (10 is highest appeal).
Ad 1: 7, 8, 6, 7, 8, 9, 9, 10
Ad 2: 3, 4, 3, 5, 6, 4, 2, 5, 4
Is there a quick statistical proof that one ad is better than the other?
