A fashion store seIls men's and women's clothing from two designer brands. Each brand designs apparel for both genders. In order to determine the brand favored by its customers, a random sample of 20 male shoppers and another sample of 20 female shoppers will be selected randomly. Each member in the sample of female shoppers will be asked to rate her satisfaction with the purchases she made from brand A on a scale from 1 to 10, and each member in the sample of male shoppers will be asked to rate his satisfaction with his purchases from brand B on the same scale. The means of the scores in the two samples will be compared to determine the brand more favored among the shoppers. Is this a proper design to conduct the survey? Yes, because the two samples have the same size. No, because the sizes of the samples are too small. No, because proportions and not means are proper statistics to use for comparison. No, because gender is confounded with brand. Yes, because the samples are selected randomly
