Sociologist have recently started to examine the growing social trend of older women dating younger men. Researchers attended two well known night clubs: The Panther Room and The Mountain Lioness. They sampled 25 heterosexual couples and discovered the average difference in the age of couples was 3.6 years with the females(x₁) being older than the male (x₂). The standard deviation for the difference in ages was 2.5 years. At the 5% level of significance is there enough evidence to conclude that the female member of the couple is older?
