Grade 7       2     3

Grade 8       1      4


Step-by-step explanation:

Given: A random sample of students from the seventh and eighth grades are asked whether they walk to school.

From the given table, the number of grade 7 students said Yes ( see 7Y) = 2

The number of grade 7 students said No (see 7 N) =3

The number of students of grade said Yes (see 8 Y)=1

The number of students of grade 8 said No (see 8 N)=4

Hence, the next table becomes

                  Yes    No

Grade 7       2       3

Grade 8       1       4
