In a study examining the effect of alcohol on reaction time, it was found that even moderate alcohol consumption significantly slowed response time to an emergency in a driving simulation. In a similar study, researchers measured reaction time 30 minutes after participants consumed one 6-ounce glass of wine. Again, they used a standardized driving simulation task for which the regular population averages μ = 400 msec. The distribution of reaction times is approximately normal with σ = 40. Assume that the researcher obtained a sample mean of 422 for the n = 25 participants in the study. Are the data sufficient to conclude that the alcohol has a significant effect on reaction time? Use a two-tailed test with a critical value of Z = +/- 2.33.
