It has generally been believed that it is not feasible for men and women to be just friends (New York Times, April 12, 2012). Others argue that this belief may not be true anymore since gone are the days when men worked and women stayed at home and the only way they could get together was for romance. In a recent survey, 186 heterosexual college students were asked if it was feasible for male and female students to be just friends. Thirty-two percent of females and 57% of males reported that it was not feasible for men and women to be just friends. Suppose the study consisted of 100 female and 86 male students. At the 5% significance level, can we conclude that there is a greater than 10 percentage point difference between the proportion of male and female students with this view? Provide the details.
