based on a study of 380 dorm residents, the 95% confifence interval for average hours slept per weeknight is from 7.2 to 7.8. That can reasonably be interpreted to mean

- 95% of all students sleep between 7.2 and 7.8 hours per weeknight

-361 (95%) of the 380 students sleep between 7.2 and 7.8 hours per weeknight

-we're 95% sure the average hours slept per weeknight by all students is between 7.2 and 7.8

-we're 95% sure the average hours of sleep per weeknight by the 380 students is between 7.2 and 7.8
