The Athletics Department at a high school is interested in the difference in the run times between 11th and 12th grade students. Suppose the 11th grade students make up the first sample while the 12th grade students make up the second. Using a confidence level of 95%, the confidence interval found was (-0.6, 3.1). Which of the following is the correct interpretation? O We are 95% confident that the run times of the 11th grade students are, on average, faster than those of the 12th grade students. We are 95% confident that the run times of the 11th grade students are, on average, slower than those of the 12th grade students. O We are 95% confident that the run times of the 11th grade students are, on average, about the same as those of the 12th grade students.
