A high school principal wanted to know if there was a difference in absences for 9thgrade, 10th grade, 11th grade, or 12th grade among students with less than a 2.0GPA. She took a random sample of n = 5 students from each grade and comparedabsences among the four grades using ANOVA. The data are below: 1.
