To test the effect of alcohol in increasing the reaction time to respond to a given stimulus, the reaction times of seven people were measured both before and after consuming 3 ounces of 40% alcohol. Do the following data indicate that the mean reaction time after
consuming alcohol was greater than the mean reaction time before consuming alcohol? Use a = 0.05. (Use uhefore - Hafter = Hg)
