Question: The Malloy and Turner Advertising Company prepared two different television commercials for Taylor women's jeans. One commercial is humorous, and the other is serious. A test screening of both commercials involved 8 randomly selected consumers who were tested for their reactions; the results are listed below:

Consumer A B C D E F G H

Humorous commercial 26.2 20.3 25.4 19.6 21.5 28.3 23.7 24.0

Serious commercial 24.1 21.3 23.7 18.0 20.1 25.8 22.4 21.4

At the 0.05 significance level, test the claim that there is no difference between the reactions to the commercials. Based on the result, does either commercial seem to be better?
