In a study examining the effect of alcohol on reaction time, Liguori and Robinson (2001) found that even moderate alcohol consumption significantly slowed response time in a driving simulation. In a similar study, researchers measured the reaction time of a sample of n = 25 participants 30 minutes after drinking a 6-ounce glass of wine which ended up with a mean of = 422 millisecond. On the standardized driving simulation task, the population scores are normally distributed with a mean of µ = 400 millisecond with a standard deviation of σ = 40. Using an α = .05, conduct a hypothesis test to determine whether these data are sufficient to conclude that the alcohol significantly increased reaction time?
