A researcher interviews random samples of men and women regarding their exposure to advertising. One variable is the number of ads to which each subject is exposed on a typical weekday. The results are shown below. Do these data provide sufficient evidence to indicate that, on the average, the sampled female population is exposed to more ads than the sampled male population? Let alpha = .05.

Group N Mean # of Ads Standard Deviation
Men 100 200 50
Women 144 225 60
