Question
1) 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 of BEFORE-AFTER was calculated) with a standard deviation of 7.22. Perform the hypothesis test that alcohol causes an increase in reaction time to a stimulus at 10% level of significance. Find a 90% confidence interval for the difference in the reaction times. (a) b)
