tailed test 14. In a study examining the effect of alcohol on reaction reaction time 30 minutes after participants consumed simulation. In a similar study, researchers measured moderate alcohol consumption significantly slowed one 6-ounce glass of wine. Again, they used a stan- response time to an emergency situation in a driving time, Liguori and Robinson (2001) found that even moderate alcohol consumption significantly slowed time to an emergency situation in a driving response simulation. In a similar study, researchers measured reaction time 30 minutes after participants consumed one 6-ounce glass of wine. Again, they used a stan- dardized driving simulation task for which the regular population averages u = 400 msec. The distribution of reaction times is approximately normal with o = 40. A ssume that the researcher obtained a sample mean of M = 422 for the n = 25 participants in the study. a. Are the data sufficient to conclude that the alcohol has a significant effect on reaction…
