Two-Way Tables -- Tutor Intake Assessment
This is a quick check on two-way frequency tables: reading them,
computing relative frequencies, and using them to judge whether two
categorical variables are associated. The goal is to see where to focus
our first sessions together, not to grade you. Work independently,
without notes.

A two-way table of curfew status versus chore status for 40
students is shown below.
| Chores | No Chores | Total | |
|---|---|---|---|
| Curfew | 16 | 4 | 20 |
| No Curfew | 8 | 12 | 20 |
| Total | 24 | 16 | 40 |
How many students have BOTH a curfew AND chores (the joint
frequency for that cell)?
