Buckling Up. The National Highway Traffic Safety Administration collects data on seat-belt use and publishes results in the document Occupant Restraint Use. Of 1000 drivers 16–24 years old, 79% said that they buckle up, whereas 924 of 1100 drivers 25–69 years old said that they did. At the 1% significance level, do the data provide sufficient evidence to conclude that there is a difference in seat-belt use between the two age groups?
