So I have a little bit of the clues for these questions, but I am kinda uncertain from question 3 and later

The following situation applies to the next seven questions: Allchanyes saved The department of motor vehicles wants to check whether drivers take a longer time to react after drinking two cans of beer. This was done by selecting a sample of 19 drivers and randomly assigning them to one of two groups. The reaction times (measured in seconds) in an obstacle course are measured for a group of 10 drivers who had no beer. The other group of 9 drivers were given two cans of beer each and their reaction times on the same obstacle course are measured. 1,What are the correct null and alternative hypotheses for this test? Use \"N\" for no beer and \"B" for two cans of beer. 0 Ho: 7N = YB vs. Ha: 7N
