Q1
A school district wants to estimate the average number of hours of sleep per night for all high school students in the district (grades 9–12). A student researcher stands in the cafeteria for two days during lunch and asks every 5th student who walks past a certain hallway entrance to report their typical sleep on school nights, collecting 180 responses. No random number generator was used, and students who did not pass that entrance during those lunches could not be selected. Which statement best describes the sample representativeness?
