    You have been told that for university classes, students are supposed to spend two hours working outside of class for each hour in class. You are curious to know the average amount of time students at your school spend working outside of class for each hour in class. You contact 100 students at your school and ask them, 'How many hours of schoolwork do you do outside of class for each hour in class?' The mean for the 100 responses is 1.2 hours.

    a.) What is the population of interest, and what is the research question you want to answer about it?
    b.) Explain in words what the population parameter is in this study, and identify the appropriate symbol for it.
    c.) What is the value of the sample estimate in this study, and what symbol is used for it?
