An 8th grade English teacher is interested in grammar scores for students coming from the two 7th grade English teachers. Scores from Teacher A 85 90 75 70 95 80 85 85 80 85 Scores from Teacher B 70 80 75 70 75 70 80 80 90 100 Is there a meaningful difference in the means for student scores on a pretest coming from each 7th grade teacher based on the samples? (If needed, round to the nearest hundredth) Teacher A: mean = MAD = Teacher B: mean = MAD = The difference in means is and is MAD's apart. As a result, I know there (is or is not) a meaningful difference.
