The article "Truth and DARE: Tracking Drug Education to Graduation" (Social Problems [1994]: 448-456) compared the drug use of 288 randomly selected high school seniors exposed to a drug education program (DARE) and 335 randomly selected high school seniors who were not exposed to such a program. Data for marijuana use are given in the accompanying table. Is there evidence that the proportion using marijuana is lower for students exposed to the DARE program?
