For each dog, the left front paw was treated with an herbal gel and the right front paw was treated with a traditional burn gel.  The burns on each paw are examined after two weeks and the mean difference in the severity of the burns in the left paw and right paw was 5.8 with a sample standard deviation of differences of 1.3.  Is there enough evidence to show that the herbal gel treatment did not work equally as well as the traditional burn gel treatment assuming that both sets of data are approximately normal?
