Final answer:
A two-way table is used to represent data for two categorical variables. It should have two rows and two columns, and the cell where the variables intersect represents the overlap between the two variables.
Step-by-step explanation:
A two-way table is used to represent data for two categorical variables. In this case, the variables are the number of people who play guitar and the number of people who play piano. The table should have two rows, one for guitar and one for piano, and two columns, one for the number of people who play guitar and one for the number of people who play piano. The cell in the table where the two variables intersect represents the number of people who play both piano and guitar.
Here is an example of the two-way table:
Play Guitar
Play Piano
Guitar 52
Piano 26
