1) Give an example of a research question that involves estimating a characteristic about the population of part-time students at your college. 2) Improve this poorly stated research question: Do students work a lot of hours?

1) what is the number of male part time students between the ages 15 - 19 years?

2) do students work more than 4 hours a day?
