Researchers recruited more than 750 adults and asked them to wear a new design of shoe. Half of the subjects were randomly assigned to a name-brand shoe, while the other half were assigned to a shoe with no name on the label. On
average, the shoes with the brand name were judged to be more comfortable. Based on this study, is it reasonable to
conclude that including the brand name on the label causes an increase in comfort?
