The U.S. National Center for Health Statistics publishes data on weights and heights by age and sex in Vital and Health Statistics. The following (sorted) weights, to the nearest tenth of a pound, were obtained from a sample of 18-24-year-old males: 129. 2, 129. 3, 147, 150. 1, 151. 9, 154. 4, 155. 8, 156. 5, 158. 1, 160. 5, 160. 7, 162, 169.7, 169.8, 173.3, 174. 6, 178. 4, 180. 7, 185, 189. 5, 214. 5, 215. 6, 217. 6, 218. 9, 219.4.
