The manufacturer of a new eye cream claims that the cream
reduces the appearance of fine lines and wrinkles after just 14
days of application. To test the claim, 10 women are randomly
selected to participate in a study. The number of fine lines and
wrinkles that are visible around each participant’s eyes is
recorded before and after the 14 days of treatment. The
following table displays the results. Test the claim at the
0.05 level of significance assuming that the population
distribution of the paired differences is approximately normal. Let
women before the treatment be Population 1 and let women after the
treatment be Population 2.
