A statistician for a drug company wishes to determine whether older adults differ from younger adults in a complex reaction time experiment involving three levels of a minor tranquilizer (Valium). Fifteen older adults (mean age 65 years, range = 60 to 75 years) were compared to 15 young adults (mean age 21 years, range = 18 to 23) on a computer task measuring reaction time. The reaction times varied on the task from 2 seconds (a very quick reaction time or a good score) to over 10 seconds (a very slow reaction time or bad score). The participants were randomly assigned to receive either 0 mg (placebo), 5 mg, or 10 mg, and one half hour later, they were tested for their reaction times in total seconds (rounded to whole numbers). Perform a two-factor ANOVA and summarize the results in a source table.
