A special issue of Newsweek in March 1999 on women and their health reported results of a poll of 757 American women aged 18 or older. When asked, “How satisfied are you with your overall physical appearance?” 30% said very satisfied, 54% said somewhat satisfied, 13% said not too satisfied, and 3% said not at all satisfied. True or false: Since all these percentages are based on the same sample size, they all have the same margin of error.
