An experimenter who is interested in the effects of pharmaceutical
commercials on mood randomly assigns participants to three groups:
a depression medication commercial condition, an anxiety medication
commercial condition, and a faucet commercial condition. After
viewing the commercials, participants report their level of
sadness. Higher scores indicate more sadness. Conduct an analysis
of variance and report the obtained F-ratio below.
