A study compares reaction times before and after drinking a caffeinated beverage. The null hypothesis (H.) in this scenario would state: The average reaction time is faster before the beverage. The average reaction time is faster after the beverage. O There is no significant difference in reaction times before and after the beverage. There is a significant difference in reaction times before and after the beverage.
