Spilich et al. (1992) ran a third experiment in which the three groups of smokers participated in a driving simulation video game. The AS group smoked immediately before the game but not during it. The data follow, where the dependent variable is an adjusted score related to the number of collisions. Run the analysis of variance and draw the appropriate conclusions.
