Hypothesis Testing - What is the average number of days missed by each student?
School A states the average number of days missed by each student is 4.0. Office personnel randomly sampled a portion of their attendance records to determine if this claim was accurate. For the previous year, the following data was obtained from the sample group, regarding absences for that year: 4, 4, 3, 2, 6, 8, 7, 1, 9, 3, 1, and 6.At the .05 level of significance, is there convincing, evidence that the number of absences per student has increased?
