Question:

Senior faculty members at a university in the USA are concerned about the number of times that students skip classes. From their very large population of students they select a random sample of 25 and check how often the students have skipped classes in the previous month. The average number of absences per student in the sample is found to be six; and the sample standard deviation is 0.6. Assuming the population of absences is normally distributed; construct a 99% confidence interval estimate of the population average number of weekly absences.
