It is believed students tend to miss 10 days of classes on average per year. Suzeen, a member of the ABC student council wasn't sure of this gure, so she decides to investigate it. She randomly picks 8 students to survey about the number of days they missed the classes. The number of days they took an off and missed classes in the past year are: 12. 4, 15. 3. 11. 8, 6, 3. Based on the sample collected by the Suzeen, should she believe the mean number of offdays taken by a student in a year is 10? Hint: since the sample is less than 30. CLT cannot be used
