Ms. Scanlon surveys her students about the time they spend studying. She creates a table showing the amount of time students studied and the score each student earned on a recent test.
Ms. Scanlon wants to understand the distribution of scores among all the students, and to get a sense of how students are performing and how much students are studying. Find the conditional relative frequencies, expressed as decimals.

- Find the total number of students represented in the table by summing the joint frequencies.
- Divide each joint frequency by the total number of students.
- Represent the conditional joint frequencies in a new table.
