The school counselors are worried about the study habits of students who are involved in a lot of after-school activities. They randomly selected students at the school and gathered the following data. Consider the number of activities the independent variable.
# OF STUDENTS | Hours Spent Studying Per Week | |
Hours of After-School | Less Than | Eight or More Hours |
Less Than | ||
Five or More Hours |
Make a conditional relative frequency table.
What is the total number of hours in each row? What is the percentage of this total for each column?

There is an association, but is it the association you would expect?
