For the Caucasian male face, x = 15.0% and s = 25.1%. The researchers reported the p-value of the test as p =. Verify that the test statistic is equal to 2.3.ī. The researchers used this sample information to test the null hypothesis of a mean level of feminization equal to 0%. For the Japanese female face, x = 10.2% and s = 31.3%. The level of feminization x (measured as a percentage) was measured.Ī. Using special computer graphics, each subject could morph the faces (by making them more feminine or more masculine) until they attained the “most attractive” face. In one experiment, 50 human subjects viewed both a Japanese female face and a Caucasian male face on a computer. Research published in Nature (August 27 1998) revealed that people are, in fact, more attracted to “feminized” faces, regardless of gender. Television commercials most often employ females or “feminized” males to pitch a company’s product.
