Assume that you reject the null hypothesis of no-difference at a=0.05. This means that you hypothesize that there is no difference in the population regarding driver satisfaction. Then, if the probability of getting a sample with your observed differences has a probability of less than 5% to be drawn from a population with no differences, you reject the null hypothesis. As a statistics expert, you O reject the null fail to reject the null wouldn't know what to do would flip a coin to decide
