The question of whether the sexual orientation of the mother has an impact on the sexual identity of her children was addressed in an article by Golombok and Tasker (1996). Twenty- five children of lesbian mothers and a control group of 21 children of heterosexual single mothers were interviewed in their early twenties concerning their sexual orientation. The results of the interviews are given in the following table. Data were unavailable for 1 male child; thus, orientation is reported on only 20 children of heterosexual single mothers.
a. What is the populations of interest in this study?
b. Is the proportion of young adults identifying themselves as nonheterosexual higher for lesbian mothers than for heterosexual mothers? Use a = .05.
c. Construct a 95% confidence interval on the difference in the two proportions of young adults who identify themselves as being heterosexual in their sexual orientation.
