The study involves dependent samples because it involves a before and after study which according to Lind et al., 2020, is the comparison of the measurements of a variable of interest before and after a certain event or condition in a study sample where the goal is to determine the difference between these two measurements.
The best statistical test to use would be the dependent sample t-test and this is so because the dependent t-test looks at two groups that are somehow related to each other by comparing the average values of these groups to see if there is a significant difference between them in different situations, also because, it helps to determine more accurately how the coffee affects the driving speeds of the drivers.
