Question
To test the effect of alcohol in increasing reaction time to respond to a given stimulus, the reaction times of 100 persons were measured. After consuming 3 ounces of alcohol, the reaction time for each of the 100 people was measured again. The mean difference in reaction time was 1.07 seconds (where the difference = BEFORE - AFTER) with a standard deviation of 7.22. a) Perform the hypothesis test that alcohol causes an increase in reaction time to a stimulus at 10% level of significance. b) Find a 90% confidence interval for the difference in the reaction times.
