The Andrew Jergens Company markets a “spa tablet” called ActiBath, which is a carbonated moisturizing treatment for use in a bath. From previous research, Jergens management knows that 60% of all women use some form of skin moisturizer and 30% believe their skin is their most beautiful asset. There is some concern among management that women will associate the drying aspects of taking a bath with ActiBath and not believe that it can provide a skin moisturizing benefit. Can these facts about use of moisturizers and concern for skin beauty be used in determining the size of the sample in the ActiBath survey? If so, indicate how. If not, indicate why and how sample size can be determined.
