Driving A research team studied the relationship between light alcohol consumption and driving when the driver is already sleep deprived. 62 men were recruited and asked to complete a simulated two-hour highway drive in the lab. They were randomly assigned to two treatment groups. Each group has 31 men. In the first group, the participants drank a glass of beer before driving. In the second group, the participants drank a glass of water before driving. The computer recorded how many times a driver drifted out of the lane. The night before their visit to the lab, all 62 participants restricted their sleep time to no more than 5 hours. See below for the summary statistics of the data. Let X be the number of times a driver drifts out of the lane during the simulated 2-hour highway drive. Let S be the sample standard deviation of X. First treatment group T1-32 S₁-3.7 I Second treatment group T2-18 S₂=2.9 S Use a hypothesis test at 0.05 significance level to answer the question: does light alcohol consumption (having one glass of beer) have a negative impact on the driving performance of a sleep-deprived driver? Assume that the conditions for hypothesis testing are met. Compute the test statistic.
