Find the Error Jasmine is interpreting data about her classmates that have an after-school job and are on the honor role. Out of 100 students that do not have a job, 67 of them are on the honor roll. Find her mistake and correct it.

Use Math Tools Survey your classmates to find out if they have a curfew and if they have assigned chores at home. On a separate sheet of paper, make a two-way table that displays the results. Then interpret the results.

Persevere with Problems The two-way table below shows the number of students with each hair color and eye color.

Which is greater: the percentage of the brown-haired students with blue eyes or the percentage of the red-haired students with brown eyes?

Model with Mathematics The two-way table at the right shows the number of hours students studied and whether they studied independently or with a study group. Write two questions that could be answered using the relative frequencies of the data in the table. Then ask a classmate to solve your questions.
