For the Parental HIV data consider the subgroup of adolescents who have used marijuana. Perform a hierarchical cluster analysis separately for females on the following variables from the Parental HIV data: the sum of the variables describing the neighborhood (NGHB1–NGHB11), enough money for food (MONFOOD), financial situation (FINSIT), and whether the adolescent likes/liked school (LIKESCH). Graph a dendrogram. If you were to decide to use four groups, how many adolescents would belong to each of the groups?
