If the sample moderate alcohol consumption significantly slowed reaction time 30 minutes after participants consumed e time to an emergency situation in a driving time, Liguori and Robinson (2001) found that e dardized driving simulation task for which the regular %3D tailed test with a = .05? time, Liguori and Robinson (2001) found the cáctic moderate alcohol consumption significantly slow even a 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 rec population averages µ = 400 msec. The distribution of reaction times is approximately normal with o = 40 Assume that the researcher obtained a sample mean of M = 422 for the n = 25…

A male and a female Judge rated the same cartoon segments for violent content. Using the data below, determine whether there is a significant tendency for the female judge to give higher ratings than the male judge. Use a one tailed test at the .05 significance level.
